What I am saying is that I have a username tim with password Passw0rd on both computers. I *am* using the right username and password, but it won't accept it. With XP, if the pc trying to connect to the destination PC was logged on using a valid matching username and password as an account on the destination PC, authentication occurred without issue.
With Windows 7, No matter what U/N I use, it won't allow me to connect.
