SUMMARY
Access to logical units (LUs) can be restricted to SNA Server and Host Integration Server 2000 clients that are running on specified workstation names. However, if the SNA Client is running in a Terminal Server session, you cannot restrict an LU based on the specific Terminal Server client's workstation or device name.
MORE INFORMATION
SNA Server 4.0
A supported feature that modifies the product's default behavior is now available from Microsoft, but it is only intended to modify the behavior that this article describes. Apply it only to systems that specifically require it. This feature may receive additional testing. Therefore, if the system is not severely affected by the lack of this feature, we recommend that you wait for the next Microsoft SNA Server version 4.0 service pack that contains this feature.

Using the SNA Manager Assign workstation to LU feature, the administrator can restrict access to an LU to SNA Server and Host Integration Server 2000 clients with a specified workstation name, IP address, or MAC address. When an SNA Server or Host Integration Server 2000 client connects to Host Integration Server, the client sends to the server the name of the computer on which the SNA Server or Host Integration Server 2000 Client is running.
If the client is running in a Terminal Server session, the client sends the name of the Terminal Server, instead of the name of the workstation that is running the Terminal Server client. Therefore, it is not possible to restrict an LU to specific Terminal Server clients or devices.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To restrict LU access to Terminal Server clients with specified names, install the hotfix mentioned earlier, and then follow these steps to add the registry key:
- Start Registry Editor.
- Locate and then click the following key in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SnaBase\Parameters
- On the Edit menu, click Add Value, and then add the following registry value:
Value name: AssignLUtoTSClient
Data type: REG_DWORD
Radix: Hexadecimal
Value data: 1 - Quit Registry Editor.
After you apply the fix and add this registry value, the SNA Client determines whether it is running under a Terminal session; if so, it will send Host Integration Server the name of the Terminal Server Client workstation, instead of the name of the Terminal Server itself.
Be aware of the following considerations:
- Disconnected terminal server sessions are not supported in this fix. If you establish a Terminal server session, disconnect from Terminal Server, and then reconnect from another workstation. The workstation name that is sent to Host Integration Server will stay the same as the first one. Users must log off the terminal server session, instead of disconnecting.
- The fix applies to all users (without exception) who connect to the Terminal Server and are running the End User client.
