Sounds like either someone moved your dc's out of the domain controlers OU, or somebody moved the exchange groups "exchange service account, exchange enterprise servers, exchange domain servers, ect..." from the users ou. Either one will cause this.

Please don't tell me to call PSS, I've been on the phone with them for 5 days and the problem is still not resolved.... I have three domains, ad.xxx.com, hcg.ad.xxx.com and hci.ad.xxx.com. Ad is the root domain, there is only one server, no exchange. Hcg has 12 Exchange servers. Four of them are Exchange 2000 (two of the four are actually clustered), the rest are 5.5 servers. Hci has only one exchange 2000 server. Everything was working fine, there were no issues with mail at all. I was getting ready to move the users onto the new boxes. On the Wednesday before Xmas, the Admin in Hci installs service pack 2 for Exchange. When he does, about 20 mins (?) later, he's getting the following error: Event 1022, Logon failure on database First Storage Group\mailbox store (HCICLEX1 (the server name)) - Windows 2000 account NT\Authority\System; mailbox (then it drills down to the Microsoft system attendant) error -2147467259. Within an hour of his call, I start seeing the same error messages on my exchange servers. When I log into the test accounts on the new exchange 2000 servers, all the sent mail sits in the out box. I installed Sp 2 on my servers, hoping the problem would clear up. Now on top of the original errors, I am getting errors telling me: Event 9175 The Mapi call "openmsgstore" failed with the following error: The attempt to log on to the Microsoft Exchange Server has failed. The Mapi provider failed. MS exchange server information store. ID 8004011d-0512-0000000 Has anyone seen anything like this?? Can someone point me in the right direction? The 5.5 servers are not affected at all. I apologize in advance for the cross post. Thanks for any advice you can give.
