Remote Server login

I got a problem a system administrator can not log on to sql remote server so he can back up the system tables. Hes doing it through active directory, not sure what the problem is. can anyone help please. reason says not associated with a trusted sql connection?Is Builtin Administrators group registered with the server with sysadmin server role? And if not, is the server configured for Mixed Security Mode? How is your admin trying to connect?|||hes logging in through windows only, not in mix mode|||Then you need to look into what account he uses and if that account is explicitly present in the Logins of the server or if its group is present there. I'd make sure that Builtins is in the logins and tell him that he should fix it himself, - include Domain Admins or his account into Local Administrators group (Builtin Administrators).|||Actually, if the BUILTIN/Administrators group is not part of SQL Server, that's a good thing. The DBA group should be the ONLY group with sysadmin rights on SQL Servers. The Domain Admins should be allowed backup permissions if that's part of their job description. Normally, the DBA does that also though.|||Well, not if you're doing replication.|||Well, I doubt they're doing replication if they can't even figure out how to log into a box. Codd, what were you thinking?|||Hey, you know we're talking about Brett here (wink-wink), Codd knows what he does there...between margaritas... :D...I'm loosing my mind...OF COURSE IT'S a WRONG THREAD!!! Oh well, eventually Brett will show up and say what I thought he already did...How many of those shots did I have?
