We have an Exchange 2003 server that yesterday quit processing email. I was able to get on it and in the event viewer there were hundreds of Event ID 1025 errors stating:
An error occurred on database "SGNAME\DATABASENAME".
Function name or description of problem: SLINK::EcTestMessage
Mixed in with these was Event ID 1000 stating that the Symantec Mail Security for Microsoft Exchange process was crashing and restarting. I disabled the SMSME service and rebooted the server and all is now well. Obvoiusly that is not a good long term solution as we now don't have mail level anti-virus running on the server. During the time that these errors were going on, emails that eventually got through were blank emails with a winmail.dat attachment.
Does anyone have any insight into this? I'm sure I'll end up calling Symantec but I hate doing that as I have little faith in their tech support from past experience.
