I have the same problem. Others can see my desktop, but I can't see theirs (I
get teh Remote Assistance Failed. Try Again." message.

I have:

1) opened port forwarding in my router for port 3389
2) checked "remote assistance" and "remote terminal" exceptions in Windopws
firewall
3) turned of the Windows firewall

Nothing worked
