SQL 2000 Enterprise manager "Cannot open user default database"

Posted on 2009-07-13
Last Modified: 2012-05-07
We have been running a SQL 2000 SP4 server for the past 4 years without any problems. SQL is running on it's own hardware on top of Windows Server 2003.

Suddenly I noticed that when entering Enterprise Manager and trying to open the local server that I would receive an authentication error. I can still connect to other SQL servers on the network and manage them successfully.

I then removed the local server from Enterprise Manager and tried to add it again, at which point I got the following error "(LOCAL) - Cannot open user default database. Login failed"
(We are using Windows authentication)

I am also unable to manage that specific server from another workstation.

All databases on the server are up and running, but I am unable to manage them at all.

I can't find anything specific to this in the event logs...

log on with a SA account and see which is the default database for the failed user. Then make sure they have the correct permissions for that database

Unfortunately we do not have the sa password for this server since we have always used Windows auth, is there some way of resetting it ?

ok when in enterprise manager, go to security under the server name, find the user who is having problems and check what their default db is. Now under user mapping check to make sure they are a member of at least "public" in that db. Either do that or change their default db to one where they do have permissions.
