I am running the same OS and Exchange Versions as you and had experienced the 
same problem a few weeks ago.  My problem appeared to be the amount of NDR 
messages in the queues caused by SPAM trying to do Directory Harvesting.  I 
believe our server was trying to send NDR to non-existent recipients thus 
causing the services issue.  I restarted our Exchange server and the services 
stayed running for awhile but outbound email from internal clients took quite 
long to get out.  I deleted all the postmaster@xxxxxxxxxxxxx messages (without 
NDR) and configured our GFI MailEssentials anti-spam software to delete any 
messages that are trying to do Directory harvesting.

Since doing this our server has been running smoothly.

Hope this helps.

PS - You should configure Symantec to Exclude all Exchange directories (exclude 
the edb and stm files as well)  I have seen databased get corrupt because of 
the anti-virus scanning.

Subject: [exchangelist] Exchange services shutting down intermittently

We're running Exchange 2000 Enterprise on a Windows 2000 server.  Small office. 
 Since Sunday last, some of our Exchange services, including WWW publishing 
have been shutting themselves off.  The services that go down are: MS Exchange 
IMAP4, MSExchange Pop3, MS Exchange Routing Engine, Simple Mail Transport 
World Wide Web Publishing Service.  

Has anyone seen this before?  Any thoughts on what might be causing it?  
Anything to do with Symantec?
