I have two computers; #1 running windows XP Home set up as a work group; #2 running windows XP Pro set up on a domain. Computer two is my laptop used in my office and computer one is my home desktop. When I connect commputer 2 to my home network, everything is fine until I turn VPN on. Once I do this, computer teo can no longer get to computer one. I get the message that the user name could not be found.
