I am running Windows Vista, and SQL Server 2005 Express came preinstalled from DELL. I have downloaded and installed the SQL Management Studio.
My windows account does not have permission as sysadmin, and cannot grant that permission to itself.
I tried to log in as SQL Server account "sa", but it says that it is not associated with a trusted connection (I'm not sure what the password would be anyway).
The windows account I am logged in as has Windows administrator permissions.
How can I setup accounts to have sysadmin permissions on this system?
