WE are facing a strange problem with the microsoft exchange server 2000 installed on windows 2003 server standard. On booting the server the connectivity between the clients and the server works fine, but after a certain period of time, the clients get disconnected one after another. On restarting the microsoft information store thru services the following errors are seen,
1. The MAD monitoring thread was unable to connect to WMI, error,
2. (End point mapper currently unavailable) Group policy processing aborted
The system also does not shut down, hence a hard reboot is done after which the network is fine only for a certain period of time.
