Win7 Remote Assistance not working with WinXPRemote Assistance Problem

I am trying to Remote assist computer on my campus. I have disabled the firewall on all computers on my domain and are currently running our own firewall that is much more reliable. All computers have remote assistance enabled. We can run it on my XP Domain Admin account and it works with other XP machines but I can not connect the win7 machine with the XP machine.

All of that NAT stuff people are trying to say works doesn't and opening windows messenger fixes nothing it won't fix or open anything that is needed for Remote Assistance.

If anyone has a real fix for this please reply.
