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.

MORE INFORMATION
The new allocated ports are: 2701, 2702, 2703 and 2704. The following table describes the new allocated ports:   sms-rcinfo    2701/tcp   SMS RCINFO sms-rcinfo   2701/udp   SMS RCINFO sms-remctrl  2702/tcp   SMS REMCTRL sms-remctrl  2702/udp   SMS REMCTRL sms-chat     2703/tcp   SMS CHAT sms-chat     2703/udp   SMS CHAT sms-xfer     2704/tcp   SMS XFER sms-xfer     2704/udp   SMS XFER To install the hotfix, perform the following steps on the Systems Management Server site server:
 * 1) In the SMS\Site.srv\ .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\ .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\ .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:
