Kernel Objects May Not Be Shared Across Terminal Services Sessions (264651)

SYMPTOMS

When a program tries to open a kernel object such as an event or a semaphore that was created in another Terminal Services session, it may not succeed. Calling GetLastError returns ERROR_FILE_NOT_FOUND.

CAUSE

This behavior can occur for any of the following reasons:

The Terminal Services server might be running in Remote Administration mode. The sharing of kernel objects is supported only when the server is running in Application Server mode. If the server is running in Remote Administration mode, this feature is disabled. You need to change the Terminal Services configuration.
The kernel object might be created or opened in a dynamic-link library (DLL) that is loaded explicitly by the program by using the LoadLibrary or LoadLibraryEx calls. Such objects are not shared across sessions even if the DLL is marked for global usage by using the register command. This article lists a fix to resolve this issue.

RESOLUTION

   -------------------------------------------------------
   06/02/2000  06:05p  5.0.2195.2096  45,328  Tsappcmp.dll

WORKAROUND

Mark the program (.exe file) that loads the DLL for global usage. Note that this works only if the Terminal Services server is running in Application Server mode.

STATUS

Microsoft has confirmed that this is a problem in Microsoft Windows 2000. This problem was first corrected in Windows 2000 Service Pack 2.
