Jeffrey,
You are right, kdestroy.exe works with the FILE:c:\temp\krbcache. The
reason I had trouble was that the destroy function in Leash32 locked the
file and went into the 99% CPU usage.
The kdestroy.exe error was from Leash32 locking the file.
It appears that Leash32 is the program that has problems with destorying
the FILE:c:\temp\krbcache ticket.

Can you provide any additional information that might be used to
replicate the problem?
