Remote Assistance App in XP

Hello,

I recently set up a home network with 2 PC’s. One is running XP Home and the other XP Pro. For some reason, the computer running XP Home can connect to the XP Professional PC with no problem. When I try and reverse it (connect to the Home computer from the XP Pro computer) it gives me this error message “The Remote Computer has ended the connection.” I am also using a Linksys 4-port router with port forwarding, but I don’t think that would have anything to do with it. As far as Iknow the Home PC is allowing Remote Assistance Connections. Anyone have any ideas on how I can connect to the Home PC using the XP Pro machine?

Thanks for your help in advance.
