I have a user getting some problem with connecting to local SQL Server 2008 default instance using windows authentication with a user which has sysadmin role and is owner of each existing database:
2010-09-28 15:40:35.04 Logon Error: 18456, Severity: 14, State: 11.
2010-09-28 15:40:35.04 Logon Login failed for user 'IIS APPPOOL\RoomViewSEWebClient'.
Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: 127.0.0.1]
