SYMPTOMS
Microsoft Windows 2000 may slowly stop responding. The following symptoms may occur in the following order:
 * 1) Any Microsoft Management Console (MMC) snap-in that is running on Windows 2000 stops responding.
 * 2) The mouse and the keyboard both stop responding.
 * 3) Terminal server sessions stop responding.
 * 4) You cannot establish new Terminal server sessions.
 * 5) Programs that are running on Windows 2000 stop responding.
 * 6) When the server stops responding, you must restart the server.



CAUSE
This problem may occur when the Client/Server Runtime SubSystem (CSRSS) process is waiting for a resource to become available. However, the resource that the CSRSS process is waiting for cannot become available because font-related semaphores are not released across the kernel/user boundary.
