Leo,

One other thing.  I just copied and executed the code to detect if terminal
services are enabled from MSDN.  It reports that they are not running.  Is
there anything else that can effect kernel object namespaces?

This is all quite strange because there was no problem with the mutexes the
last time the applications were tested (about 3 months ago).
