Symptoms

Client computers may experience conflicts between ports used by the Systems Management Server Helpdesk function and by other applications. The existence of a conflicting port can manifest itself in various ways, including, but not limited to, general protection (GP) faults on the client computers, application errors, and the Remote Control Agent hanging.

The Systems Management Server Helpdesk function uses the following ports during its operations:
   Purpose                    Port
   -------------------------------

   Verification of Rights     1761
   Remote Control             1762
   Remote Reboot              1761
   Remote Chat                1763
   File Transfer              1764
   Remote Execute             1761
				
Use the following steps to determine if a conflict exists:
  1. Disable the Systems Management Server Remote Control Agent (Wuser32.exe).
  2. Restart the computer.
  3. Run the command netstat -a.
If the above ports are listed (TCP and/or UDP) then a conflict exists.

Cause

The UDP/TCP ports cannot be shared between applications.

To install the hotfix, perform the following steps on the Systems Management Server site server:
  1. In the SMS\Site.srv\Platform.bin directory on the site server, replace the Sightnt.dll file with the version obtained from the hotfix.
  2. In the SMS\Site.srv\Maincfg.box\Client.src\Platform.bin directory on the site server, replace the Wuser32.exe, Chat32.exe, and Wslave32.exe files with the version obtained from the hotfix.
At the next Maintenance Manager work cycle, the files are replicated to the SMS\Logon.srv\Platform.bin directory on all Systems Management Server logon servers. Subsequently, new clients get the new .exe file and the existing clients can be updated. To update the existing clients, either manually run Upgrade.bat on each client or follow the instructions in the following article located in the Microsoft Knowledge Base:
