I’m facing some strange issue when troubleshooting the user connectivity issue.
User not able to connect to SQL Server but he can able to RDP to the machine ,however user id is already part of AD domain group with enough permission on the database instance.so there is no issue with AD level
But still user not able to connect to the Database and getting the below error message ,even user tried with runas administrator but no luck..
Login failed for user ‘Microsoft\DBA’ . Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: <local machine>]
Error: 18456, Severity: 14, State: 11.
Please kindly let me know how to troubleshoot this issue further (Pls don’t say its UAC part)
Thanks in advance!!
