SMS: Ending a Remote Control Session Leaves Open Handles

• Microsoft Systems Management Server, version 1.2

SYMPTOMS

When opening a remote control session with a client computer running Windows NT, multiple handles are opened on the Windows NT client. Upon closing the remote session, four handles are left open. Each time a session is opened and closed, the number of open handles increases by four.

Additionally, there is a small memory leak in the Working Set memory used by the process.

Both resource leaks are very slow, and only affect systems that are remote controlled very frequently and are restarted rarely.

WORKAROUND

To work around this problem, stop and restart the Systems Management Server Remote Control Agent service (Wuser32.exe). Doing this returns the reserved resources back to the operating system.

STATUS

Microsoft has confirmed this to be a problem in Systems Management Server version 1.2. This problem was corrected in the latest Microsoft Systems Management Server version 1.2 U.S. Service Pack.
