You should be able to use a net use connection if you are running Windows NT and connection to an NT box.

Net use * \\anotherserver\sharename /user:othername yourpasswordgoeshere

The above command will allow you to log in to a different domain as a different user. You can swap the asterisk for a drive letter if you prefer.
