I have 2 computers linked in a network. One computer uses WIN98SE, the other WIN2000. Until recently I was able to message the computers; using WINPOPUP.EXE from the WIN98 computer, and Net Send from the other.
Suddenly, I am only able to communicate 1-way. I can send a message from the WIN2000 computer and it will be received by the other, but the reverse doesn't work.
Each computer recognizes the other as part of the network; they are both part of the same Workgroup; and I can ping each computer from the other. I can share files, etc. with no problems.
I am using ZoneAlarm as my firewall, and if I turn it off, I can communicate 2-ways. The problem seems to lie with the ZoneAlarm settings on the WIN2000 computer. I have checked the firewall connections in the ZoneAlarm program, and I have, in both cases, the other computer's IP address as being in the "Trusted Zone". Nevertheless, the WIN2000 computer can neither send nor receive messages. The WIN98 computer indicates, though that the message has been successfully sent when I send from it.
Any ideas?
