Hi, I have a ad 2008 r2, with exchange 2010 cas/hub/mailbox. complete fresh setup no upgrade scenraio on ad or exchange. Randomly my exchange server while logging on gives this error : the security database on the server does not have a computer account for this workstation trust relationship some times it logs in properly some times the error arises. i searched a lot but most of them have suggested to remove from domian and join again, but i guess this will not help as exchange is in place. need help on this. Regards, Kiran B.

When citing an entry in the event logs, please post the entire event log entry. You are welcome to use the handy-dandy "copy to clipboard" button in the event log detail window to assist you with this. Also, what service pack and rollup hotfix level are you running? If the problem is intermittent, then you may be having problems with your domain controllers. Try running DCDIAG on your DCs; maybe you'll find something wrong.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
