Configuring NetSupport PC-Duo

The behavior of both Clients and Controls in NetSupport PC-Duo is determined by profiles. These give administrators a high degree of control over the actions that users can take, and the security measures employed on both Clients and Controls. Furthermore, because the system can support multiple profiles, they also give administrators the flexibility to define individual and group profiles, and so place restrictions only where they are needed. This first section in this chapter describes how to create and work with profiles for Clients; the following section describes how to create and apply profiles for Controls.

Client profiles always take precedence over Control profiles. This enables NetSupport PC-Duo to support users who handle sensitive information, without compromising their ability to maintain data security.

Configuring Clients

NetSupport PC-Duo Clients use a configuration file, called CLIENT32.INI, to store their settings. Use the NetSupport PC-Duo Client Configurator application to specify the Client settings.

Using the Configurator, you can specify the following Security features:

Use NT Security

Windows NT4, 2000 and XP Clients can be configured to ensure that Controls which want to connect to the Clients are valid users.

Security Keys

Given a compatible network transport, and the correct user name and password, a Control user may be able to access Clients on your network. However, a Security Key prevents any unauthorized Control from connecting to Clients. In its simplest form, the Client allows connections only from Controls which have a matching license serial number. Arbitrary Security Keys can also be applied.

Audit Trailing

All Clients can use the Client log file to record connection operations performed on them by Controls. Windows NT, 2000 and XP Clients can also record Control operations in the Application Event Log.

User Acknowledgement

This option prompts the Client to approve an attempted connection by a Control. Using this option prevents a Control from accessing a Client PC while there is no user present. User Acknowledgement can be disabled when a Windows NT4, 2000 or XP Client is logged off.

Customizable Restrictions

You can customize a Client Profile so that a wide variety of restrictions take effect when a Control connects to the Client. These include Disable Watch / Share / Control, Blank Client Screen, Disable file transfer (whilst still allowing connecting and viewing), Restrict Drive / Directory / File Access, Keep connection indicator on top (ensures the connected indicator does not become obscured on the Client desktop) and Force Compression/Encryption (to prevent the unwanted tapping-in of the connection with a data analyzer).

When you start the Client Configurator, you are prompted to use either the Basic Configurator or the Advanced Configurator:

The Basic Configurator

enables you to specify the Client's Transport, General, Bridge and Audio settings. Use this method of configuring Clients if you are new to NetSupport PC-Duo, or if you just want to specify the network transports or basic security settings for a Client.

The Advanced Configurator

offers full access to the Client configuration file. Use the Advanced Configurator if you want to create multiple Client Profiles, set up Client access restrictions or configure advanced security options for Clients. You can also use the Advanced Configurator to specify the individual Client Parameters for a PC.

Starting the Client Configurator

If you have just installed the NetSupport PC-Duo Control application, you can choose to start the Configurator at the end of the Installation Process (see "Completing the Installation Process"). Alternatively, you can start the Configurator at any time from the Start menu.

To Start the Client Configurator:

Click the Start button in the Windows Taskbar to display the Start menu, then display the contents of the Start, Programs menu.
Choose the PC-Duo submenu, then choose the Client Configurator command. The Client Configurator Welcome dialog is displayed.
Read the information in the dialog and click the Basic button or the Advanced button.

Do not use the Basic Configurator if the Client configuration file is using Multiple Client Profiles. A warning message is displayed if you try to start the Basic Configurator when you have multiple Client Profiles.

Using the Basic Configurator

The Basic Configurator allows you to view and amend the basic configuration settings for the Client. The information in the Basic Configurator dialog is contained in four pages:

Transport

enables you to specify which network transports you want the Client to work on. Use the Test buttons to check the network transport information.

General

enables you to specify a password and other basic security options for the Client.

Dialin Bridge

enables you to specify network protocol and security options for Clients used to provide dialin access for Control PCs on remote networks. (For more information, see "Using a Client as a Bridge".)

Audio

enables you to configure microphone and speaker volume levels for use in Audio Chats.

To Configure Clients using the Basic Configurator:

Choose the Client Configurator command from the NetSupport PC-Duo Program Folder, then click the Basic button to open the Basic Configurator dialog.
Specify the options and settings in the Transport, General, Dialin Bridge and Audio pages of the dialog and click the OK button.
A message dialog is displayed asking if you want to restart the Client. Click the appropriate button in the message dialog.

Using the Advanced Configurator

The Advanced Configurator allows you to create multiple Client Profiles, set up Client access restrictions and configure advanced security options for Clients.

Working with Configuration Files:

CLIENT32.INI configuration files are usually stored in the directory in which NetSupport PC-Duo was installed.
Use the toolbar of the Advanced Configurator window to create a new configuration file, open an existing configuration file, and save the current configuration file.
Clients can be set up with pointers to more than one configuration file. For example, they can reference a configuration file which is stored on a server by default, and access a local configuration file it the remote file is unavailable. This enables multiple Clients to share the same configuration file.

To specify which configuration files are referenced by Client PCs, use the Advanced Configurator to edit the Client Parameters. For more information, see "Selecting Configuration Files".

Working with Client Profiles:

A configuration file consists of one or more sections known as Profiles. Each Profile contains configuration information for the Clients that use the configuration file.
The Master Profile at the top of the list cannot be moved, as it contains the general settings for the Client. (The Master Profile contains more settings than other Profiles.)
Other Profiles can be created, which contain different settings for specified Control users. By default, most editable settings are inherited from the Master Profile (for example, inherited check box settings are shown as a check with a gray background) so you need update only the settings you want to change.
The Advanced Configurator window lists Client Profiles in priority order, with Profiles at the top having the highest priority. When a Control tries to connect to the Client, the Client starts from the top of the list and tests each Profile until it finds a Profile that permits access to that Control, or until it reaches the end of the list. (If the Client does not find a suitable Profile, the connection is denied.)
To change the order of Client Profiles in the Advanced Configurator window, select a Profile and click the Move Up or Move Down button in the toolbar.

Viewing and Editing Client Profiles

Use the Advanced Configurator to view and edit the individual Profiles that make up a configuration file. The Master Profile contains twelve pages:

Transport

A Client can be accessed by Controls through more than one network transport. Use this page to assign and test the available transports.

Users

Specifies which Control users can connect to the Client.

Security

This page contains additional settings for specifying how Controls can connect to the Client.

Remote Control

Specifies how the Client is viewed by a Control.

Options

Restricts the NetSupport PC-Duo Functions which are available to the Control when working with the Client.

Protect Configuration

Protects the Client Configuration settings by applying user validation and password protection to the configuration.

Web Extensions

Configures Clients to act as a simple web servers using the TCP/IP transport.

Client Connect

Specifies the Controls to which a Client can connect.

File Transfer

Sets up access rights (such as Write, Read, Execute and List Directory Contents) for specified files and directories on the Client PC.

Customise

Customizes how the Client application is displayed on the user's PC.

Dialin Bridge

Configures the network protocol and security options for Clients used to provide dialin access for Control PCs on remote networks.

Audio

Configure microphone and speaker volume levels for use in Audio Chats.

The settings for other (non-Master) Profiles are displayed in a dialog containing five pages:

Users

Specifies which Control users can connect to the Client.

Security

Additional settings for specifying how Controls can connect to the Client.

Remote Control

Specifies how the Client is viewed by a Control.

Options

Restricts the NetSupport PC-Duo Functions which are available when working with the Client.

File Transfer

Sets up access rights (such as Write, Read, Execute and List Directory Contents) for specified files and directories on the Client PC.

To View or Edit a Client Profile:

Select the Advanced Configurator window, select the Client Profile you want to work with, then click the Edit button in the toolbar.
The Profile dialog is displayed. Its title contains the path of the current CLIENT32.INI file, and the name of the Profile you are currently viewing. This dialog enables you to view and edit the various settings for this Client Profile.

If you want to restrict the Profile to specific Control users,:

Select the Users page, and click the Change button to open the Valid Usernames dialog.
Use the buttons in the Valid Usernames dialog to enter the names of users who can access Clients using this Profile.

Use the other pages in the Profile dialog to control which features are available when the specified Controls connect to the Client.
When you have finished editing the current Profile, click the OK button to return to the Advanced Configurator window.

When specifying the Control users who are associated with a Profile, use an asterisk character ( * ) as a wildcard to denote all Control users. You must specify an asterisk when using Windows NT security.

If you select the Authenticate User and Password with NT check box in the Users page, any Control users attempting to connect using this profile must enter a valid NT username and password.

Alternatively, to enter the names of NT groups, use the Restrict Access to Members of the following Groups field. Use the Browse button to select the groups rather than typing them.

The Copy button in the toolbar enables you to create a copy of the currently selected Client Profile.

You can use the Rename button in the toolbar to rename the currently selected Client Profile.

Configuring Clients for ActiveX Connections

In addition to communicating with Clients from the NetSupport PC-Duo Control, you can connect to them and control them through a web page using ActiveX. You can connect to any PC running the NetSupport PC-Duo Client application using Internet Explorer 4.0 or later. You do not need to install the NetSupport PC-Duo Control application to connect to a Client using this method.

To Enable the Web Extensions on a Client:

Choose the Client Configurator command from the NetSupport PC-Duo Program Folder, then click the Advanced button to open the Client Configurator dialog.
Double-click the Master Profile to open the settings dialog.
Click the Web Extensions page and select the Enable Web Extensions check box.
By default, the ActiveX connection uses Server Port 80. If you are already using port 80 to run a personal web server or IIS, type the next available port number in the Server Port field.
Click OK to close the dialog.
Save the Master Profile and close the Client Configurator window.
Restart all the Clients that you want to access using ActiveX.

For information on how to connect to a Client using ActiveX, see "Connecting to Clients using ActiveX".

Adding New Client Profiles

To Add a New Profile:

Select an entry in the list to specify where you want the new Profile to appear. The added Profile is positioned directly beneath the selected Profile.
Click the Add button in the toolbar.
In the Add New Profile or Include File dialog, ensure the Profile Name option is selected, then enter a name for the Client Profile in the text field.

Click the OK button to add the section and return to the Advanced Configurator window. You can now select the new Client Profile from the list and use the Edit button to configure it.

You can also add a new Client Profile by selecting an existing Profile and choosing the Profiles, Add menu command.

Deleting Client Profiles

To Delete a Client Profile:

Select the Client Profile you want to delete from the Advanced Configurator window.
Click the Delete button in the toolbar.
In the confirmation dialog, click the Yes button to delete the Client Profile.

You can also delete a Client Profile by selecting the Profile and choosing the Profiles, Delete menu command.

Selecting Configuration Files

By default, a separate CLIENT32.INI configuration file is stored on each PC when you install the Client kit. However, to reduce the maintenance overhead, you can use central configuration files to ensure that Clients use the same configuration parameters.

To create a centrally stored configuration file:

Create a share with appropriate access permissions for all Clients that will use the central configuration file.
Save the configuration file (CLIENT32.INI) to the share.

To configure Clients to use the central configuration file:

Open the Client Configurator from the Windows Start menu, and click Advanced.
In the Client Configurator window, choose Client Parameters in the Profiles menu to open the Client Parameters for this Machine dialog.
If the central file is located on a PC running Windows NT4, 2000, or XP:

Click Add to open the Add/Edit Client Parameter dialog.
Select the User Credentials option, then enter the Username and Password details of the user account which this PC can use to access the central configuration file.
Click OK to save your changes and close the dialog. The user details are displayed in the Client Parameters for this Machine dialog.

Due to the lack of operating system security, there is no need to supply user credentials when the configuration file is located on a PC running Windows 95, 98 or Me.

Click Add to open the Add/Edit Client Parameter dialog again.
Select the Configuration File option and enter the location and name of the configuration file, or click Browse to search for the file.
Click OK to save your changes and close the dialog. The location details are displayed in the Client Parameters for this Machine dialog.

Click OK to save your changes and close the Client Parameters for this Machine dialog.

You can specify more than one configuration file parameter. This enables a networked Client to use a shared CLIENT32.INI file by default, but still use a local file if the server is not available when the Client starts.

Because the Client must open a session on the server before it can locate the configuration file, the user credentials parameter must always precede the associated location parameter if it is required. To reorder the list, select a parameter and click Move Up or Move Down.

Disconnecting Controls from Clients

If Clients need the ability to disconnect from any connected Controls, you can remap the Client's Request Help hot key combination to disconnect it without warning. This enhancement removes the need to use the Client's Commands Disconnect menu command, which can be prevented by Control users.

This procedure removes the Client's ability to use a hot key combination (ALT+LSHIFT+RSHIFT, by default) to request help from a Control.

To enable the hot key disconnect:
Open the CLIENT32.INI file and locate the [Client] section of the configuration file.
Add the following line to the [Client] section:
 DisconnectHotkey=1
To reset the configuration file's checksum, open the Client Configurator in Advanced Mode, then open and save the file.
Restart the Client32 Service to apply the change using the Restart Client shortcut, or RESTART.BAT.
Exiting the Advanced Configurator

To Exit the Advanced Configurator:

Choose the File, Exit menu command, or click the close button in the top right corner of the Advanced Configurator window.
If a message dialog is displayed, asking if you want to save the changes to the Configuration file, click the appropriate button.
If you have made any changes, a warning message is displayed. Select the Restart option to apply your changes.

Using Control Profiles

Control Profiles are named configurations used by the Control application. They store security settings as well as additional settings, such as the network transports required to access Clients. They also enable a Control user with NetSupport PC-Duo administrator rights to set up profiles for other Control users. These profiles contain permissions which determine the level of access which Control users can have to Client PCs.

The Control profiles are stored as registry entries under Windows. Normally, they can be amended only by a NetSupport PC-Duo Administrator with the required access levels. Under Windows NT, 2000 and XP, Administrator privilege is required to amend the User Profiles.

Control users are able to access only the NetSupport PC-Duo functions which their profile permits; users without Administrator rights cannot change their profile. As a result, you can create secure, password-protected Control Profiles which determine the levels of access Control users can have to Client PCs. For example, one Control user may be profiled to have Connect and Watch functionality only, whereas another Control user may have full functionality.

Client profiles always take precedence over Control profiles. This enables PC-Duo to support users who handle sensitive information, without compromising their ability to maintain confidentiality.

Security features which you can implement in Control Profiles include the following:

Password (General page)

Sets an encrypted password, which must be entered before a profile can be selected.

Security Key (General page)

Sets a security key, which is sent to Clients upon connecting. If this does not match the security key at the Client (if one has been set), the connection will be refused.

Prompt for Additional Information when Connecting (General page)

When the User Acknowledgement required option is set at the Client, this setting defines an additional message, which is displayed at the Client. For example, it could be the name and telephone number of the Control user who is trying to connect.

Use Compression (General page)

Select this option to ensure that all data sent using this Control profile is compressed.

Use Encryption (General page)

Select this option to ensure that all data sent using this Control profile is encrypted, including any keystrokes. Select an entry in the Type list to specify what type of encryption you want to use.

Because only 56 bit (DES) compression was available in previous versions of PC-Duo, you must use this option when a profile is used to connect to Clients running older versions of the software.

Blank Client Screen (View page)

Blanks the Client PC screen when it is being controlled, so the Control user can perform actions without being observed by Client users.

Additionally, you can implement a wide variety of restrictions for a Control Profile in the User Interface page of the Settings dialog:

Hide Client List / Client List Read Only

NetSupport PC-Duo maintains a list of Clients to which the Control has previously been connected, along with their network addresses. The Hide Client List option prevents the list from being displayed in the Control application. The Client List Read-only option prevents the list from being amended.

Hide Group List / Group List Read Only

The Hide Group List option prevents the Group list from being displayed in the Control application. The Group List Read-only option prevents the list being amended.

Hide Dial Directory

Disables all Remote Networks functions. The Remote Networks branch is removed from the Tree View, and all related menu items and toolbar buttons are removed.

Dial Directory Read-only

Removes the ability to alter the Remote Networks list. The Remote Networks item is still available in the Tree View, but users cannot create or modify.

Disable Browse

Prevents the automatic discovery of NetSupport PC-Duo Clients.

Disable Share / Disable Watch / Disable Control

These options limit the functions which the Control user is able to perform when connected to Clients.

Disable Show

Prevents the Control from showing their screen to Clients.

Disable File Transfer

Disables NetSupport PC-Duo's File transfer capabilities for this Control profile.

Disable Chat

Prevents the Control user from using the Chat feature.

Disable Send Message / Disable Broadcast Message

Disables the message functions at the Control.

Disable File Manager

Prevents Control Users from opening the PC-Duo File Manager.

Disable Reboot

Disables the ability for the Control to remotely reboot Clients.

Disable Replay

Prevents the Control from displaying Replay files. The Replay function is an option that records all activity while a Control is connected to the Client. The file can be replayed and used to audit all activity that took place.

Disable Execute

Prevents the Control from running applications on Clients.

Disable Registry Editing

Prevents the Control from editing the Client registry except under remote control.

Disable Blank Screen

Prevents the Control from blanking out Client screens during a Control session.

Change Settings

Prevents the Control user with this profile from changing their default settings.

Configure User Interface

Prevents Control users with this profile from changing the functionality that is available to them.

You cannot delete a Profile that is currently in use. If you want to delete that Profile, you must first select another Profile.

Recording and Replaying Control Sessions

NetSupport PC-Duo Clients can be configured to automatically record the actions performed when a Control connects to it. The recorded file can then be replayed by a Control.

You can also configure a Control to record Remote Control sessions, using the options in the Settings for Configuration dialog's Print Capture and Replay page.

Configuring Clients to Record Control Sessions

You can amend a Client's configuration file to specify where recorded Remote Control sessions are stored.

Any Clients which have their configuration file changed in this way are able to record Control sessions, after they have been restarted. (Configuration files are only referenced when a Client starts.)

To Configure a Client to Record Control Sessions:

In the Windows Start menu, choose the Programs, NetSupport PC-Duo Client Configurator command.
In the NetSupport PC-Duo Client Configurator dialog, click the Advanced button.
In the Client Configurator window, ensure the appropriate CLIENT32.INI file is loaded.
Select Master Profile in the list, then click the Edit button in the toolbar.
In the CLIENT32.INI dialog, select the Options page.

Select the Record Replay Files check box, and use the In Directory text box to specify where the files are saved. Alternatively, click the Browse button to select the directory, rather than typing it.
If you want to restrict access to recorded control sessions, click the Set button to enter a user name and password for the recordings directory.
Click the OK button to return to the Configurator window.
Click the Save button in the Configurator window's toolbar, then exit the Configurator application.

If the CLIENT32.INI file is used by more than one Client, you can use the Set button to display the Add/Edit User dialog. This dialog enables you to set only specified Clients to record Control sessions.

When a Client is configured with these options and restarted, Control sessions are recorded and stored in the specified directory files with an .RPF extension.

You may want to store recorded Control sessions in a secure area on a server.

Replaying Control Sessions

You can replay a recorded Control session using the NetSupport PC-Duo Control application. (It does not need to be the same Control that recorded the session.)

When viewing a Control session, remember you are watching a recording of the actions performed by a Control. The actions are not repeated on the Client.

To Replay a Control Session:

In the Control window, choose the Tools, Replay menu command.
In the Open dialog, locate and select the file you want to replay. When you select a Replay file, information about the file is displayed at the bottom of the dialog.
Click the Open button. The recorded control session is displayed in the Replay window.

Using the Replay Window

The Replay window is used to display recorded Control sessions.

The Replay window has two buttons in its toolbar:

The Scale to Fit button enables you to display all of the recorded session in the Replay window. This eliminates the need to scroll to different parts of the window.
The Full Screen button enables you to make the Replay window fill the entire Control screen.
Both of these buttons act as toggles. Click them a second time to return the Replay window to its previous state.

The Replay Controls window is also displayed when you are replaying a Control session.

The Replay Controls window enables you to navigate the Control session which is being displayed in the Replay window:

The gauge bar at the top of the Replay Controls window shows the progress of the recording. This gauge is divided into set intervals, with units of minutes and seconds.
Information about the current Control session is displayed at the bottom of the Replay Controls window.
The buttons enable you to control the display of the replay:
Play / Stop Starts and stops the Control session. The button changes to Stop when the Control session is playing. The button changes to Play when the Control session is stopped.

Rewind Start playing the file from the beginning if it is already playing; otherwise, moves the replay index to the beginning of the file.

Skip to Previous Moves the replay index to the previous activity marker, or to the beginning of the file. These markers are added at points where lots of activity was recorded at the Client.

Frame Advance Advances the replay index to the next frame. Click and hold this button to Fast-Forward though the replay file.

Skip to Next Moves the replay index to the next activity marker, or to the end of the file.

When you have finished watching a Control session, choose the File, Close command to exit the Replay window.

Security for Dial-Up Links

Dial-up support is provided by the NetSupport PC-Duo Bridge programs. These enable access to Client PCs on which the Bridge utility is running, or to any PC on a network which has a Client loaded and Bridge utility running.

Because the NetSupport PC-Duo Bridge claims the serial port, it is very secure. It has been tested with products that use the serial port as a back door to gain access to a PC, and has proven to effectively lock these out. The Bridge utility can be configured to support the following security functions:

Access Password

Requires the user at the Control PC to enter a password before access is permitted. The password is encrypted at the Client end. This feature is in addition to any Client password restrictions already in effect.

Dial-Back

This function causes the Dialin Bridge to dial-back the Control PC according to the password entered by the Control when attempting to connect. You can associate different telephone numbers to different passwords, enabling you to set multiple dial-back numbers.
