Can't connect to SQL Server in different domain using SSMS and Windows 7 Credential Manager

Question

I need to connect to a SQL Server 2008 instance in another Windows domain to manage it. We only use Windows Authentication.

In Windows XP, I could use the \"Manage

Answer 1

It looks like there is a bug in the Windows 7 Credential Manager that causes this behavior. After lots of Internet research, I found some ugly workarounds, but also found a great one:

In Credential Manager, add an entry for the remote server, but instead of adding just the server name, like database.contoso.com, add the server name with the SQL Server port, like so:

database.contoso.com:1433

This results in the desired behavior, with no pain!

Also remember, of course, that you need to prefix the remote username in Credential Manager with the remote domain name, like so:

database\administrator
