Exchange 2003 running on Server 2003, 4 Gig RAM, boot to disk, databases are on SAN, 6 months old.
Receiving several hundred Event ID 12800 errors on this particular server.
What I've done:
Removed all instances of Symantec, according to MS, they saw some excesive symantec hooks. That did not help. Stopped ALL other non MS services, rebooted and tested, same error. Removed the RAM and replaced with identical from spare server, no luck.
I noticed on one of MS's KB's that this could be due to a corrupt attachment.
Since I have several thousand users on this box, how can I determine WHO (if any) has the corrupt attachment? I have defragged the databse, still no joy.
