The server is SQL 2008 R2.

I have a SQL server setup with mixed mode authentication but I can only login as the sa user.  I can't access it with my AD credentials.  I have verified the login setting against another server that works fine.  I have added domain\Domain Admins as a Login and assigned the sysadmin role and made sure it was grnated permission to connect.  The error shows a state code of 11, but I havne't had much luck finding a resolution on Google.
