SYMPTOMS
A program that is running in a terminal server session may stop responding (hang).



CAUSE
In rare instances, a thread in Win32k.sys may enter an endless loop while looking for a window. The amount of kernel time for this program will be very high and continue to increase because the thread is almost always actively running in the kernel.
