Exchange server 2003 won't let me create any new mailboxes
After updating my windows 2003/exchange server 2003 box a couple of weeks ago i have been seeing a weird error in my event logs every night at around 2am.
Event ID - 1233 sourse-MSexchageIS
An error occured
Function name or description of problem:
ScHasServerExpired returned error
Now today i went to create 2 new accounts and for some reason i can't login to the mailboxes. I can login to the new user accounts but when i check i can see there is now email addresses populated for the new users or mailboxes created under system manager.
I can't see anymore events in event veiwer to help me see what the problem is?
Windows 2003 SP1 and Exchange Server SP2. (exchange running on the DC)
