Our old Small Business Server 2003 (acting as our domain controller) was on the fritz, so we replaced it with a new Windows Server 2008 box and set the server up as our new domain controller. In hindsight, it may have been a mistake, but we set up the new server as a replacement and tried to keep as much the same as possible, including the DOMAIN name. The problem was, that even though the domain name was the same, the guest computers somehow still realized it was not the exact same domain. We had to unjoin and rejoin the domain and port over everyone's documents and settings.
This morning, when I attempted to connect to my local SQL Server Instance, it was saying that my login failed. When I tried to use the SQL Management Studio, it throws the error "Package 'Microsoft SQL Management Studio Package' failed to load" on startup, then exits without giving me a chance to change the login. I am using Mixed Authentication and have an administrative account as a backup.
Ideas? If there is a more appropriate stack, please let me know where to put it.

Try logging in as the SQL
sauser and changing the server logins so your Windows user has permission to log in.Windows doesn't just use the domain name, there's all sorts of GUID's it uses internally, which is also why your client computers knew this wasn't the same domain as before. Your SQL installation is probably referencing your user GUID from the old domain and not this new one.
You might also want to check the account you're trying to log in with isn't locked out, both in Active Directory and SQL.
