I installed the newest ZA Free and now one of the 3 computers on my home network cannot talk with any of the others and they can't talk with it. AND I keep getting this message:

I know that I must be REALLY dumb, but I believe this to be related to my inability to communicate with my 3rd computer, HOWEVER, I can't figure out how to set the firewall on both computers to allow access to the network.

I am running Windows XP SP3 on both computers.

I cannot gain access to MSHome group of computers on the remote.

Help!?!?!?!
