Aloha Cliff,
From what I've been able to determine so far, the person giving Remote
Assistance doesn't need to be concerned about port forwarding. Only the
person receiving the RA if he(she) is behind a router. In my case the
receiver is not behind a router and I can connect to him with other Pcs
behind my router, but my PC generates the "Remote Assistance Failed" message.
That pretty much leaves some setting or registry value that got changed or
corrupted in WinXP.
I'm glad you tagged onto my post and hope someone in the know will get us
some help. I'm pretty sure there are others having this problem. I've been
pretty dilligent in trying to find a fix and I think exhausted all I can
think of short of the "Pay per incident" from MS (which hasn't proved very
helpfull in the past). HELP, PLEASE
