Please verify that the following services configured in the cluster start
successfully on the server:
1. IMAP4Svc
2. MSExchangeIS
3. MSExchangeMGMT
4. MSExchangeMTA
5. POP3svc

In case either or all of the above processes terminate, they are automatically
restarted after 5 seconds. In case they terminate more than 3 times in 1 hour, the
server is rebooted automatically.
This completes the configuration for monitoring the Microsoft Exchange 2000
Server processes.
