I installed MS SQL Server 2005 on my computer. I am using Vista. After installation, SQL Server was giving a compatibility error so I downloaded/installed SQL Server 2005 server pack 1for vista. Now, I can't login to SQL Server.
It gives the error:
Login Failed for User ". (Microsoft SQL Server Error: 18456
I also have MS SQL Server Express installed on my computer and I can login to that without any problem.
Any ideas? thoughts?
