On a highly stressed Exchange 2000 computer, the system attendant (Mad.exe) may silently stop running. No crash dump file is generated, and no event ID error message is logged in the event logs.
However, if a debugger is attached to Mad.exe, the process stops responding in the debugger with the following stack trace:

This problem may occur if a Named Service Provider Interface (NSPI) and an RFR client access DSPROXY at the same time, shortly after a domain controller that Exchange 2000 uses shuts down. The DSProxy may cause an unhandled exception that can silently stop the system attendant (Mad.exe).
