Brand new installation of SQL2008 R2.
My user, xxx, is a domain admin.
I am attempting to connect via management studio while directly logged onto the SQL box.
If I specifically add that user to SQL Logins then I can connect OK.
However, if I add the group DEV\Domain Admins as a login I get the error above. Further, in the SQL log I also see: Login failed for user DEV\xxx. Reason: Token-based server axxess validation failed with an infrastructure error. Check for previous errors. [CLIENT: ]
