The XYZ group has around 10 users in there who are successfully able to access the SQL Server database. I recently added a new user to this group (at AD level), but this person is not able to access SQL Server (through Mgmt Studio) and he's getting the error below Login failed for user. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. Error: 18456, Severity: 14, State: 11. I have already verified AD permissions are setup properly, user has restarted his machine, he is not part of any group that has DENY access and the SQL Server XYZ group has been removed and readded to the SQL Server instance in Mgmt Studio and server has been restarted. Any ideas on how to proceed further?

I fount the cause of the problem. I just whished the MS error message in the logs could be more clear. The remote user with logging access problems was also part of a group that was denied access to our database. I completely overlooked this configuration. I then created a different group and granted access to the user. I also granted access explicitly and in both instances the users was denied access. Once I remove the group that denied access it all worked fine. p.reinoso Marked as answer by Pedro Reinoso Wednesday, July 14, 2010 2:52 PM Wednesday, July 14, 2010 2:52 P

What happens if you add the users directly, or add them to a domain group (Vs. a local group?) Sounds like domain trust/delegation issue... The probability of survival is inversely proportional to the angle of arrival.
