When you attempt to stop the Microsoft Exchange Server System Attendant service, the following error may occur:
The service cannot accept control messages at this time.

Microsoft Windows NT
ID no 0xc0020425
If you try to stop the service manually with the following command
the following error message appears:
The service cannot be controlled in its present state.
In Event Viewer there is no indication of problems with the service.


The System Attendant service has become unstable.


To work around this problem of the service being in an "uncontrollable" state, do one of the following:

  • Restart the server to allow the service to be forcibly shut down and restarted with the server startup.

  • Use the Windows NT Resource Kit tool Kill.exe to terminate the Mad.exe process. Please refer to the Resource Kit documentation for more information.
