Some registered broadcast hosts have disappeared
I've been running Xmanager 1.3.9 for a while, with 4 hostnames registered in my XDM Broadcast. Each of the hosts is on the same subnet to eachother, but on a different subnet to my PC. Until recently, when I opened Xmanager, I would see all the registered hosts and was able to connect to all of them just fine.
About 2 weeks ago, all but one of the hosts disappeared off the broadcast list when I start up Xmanager (they all disappeared at the same time). I had not made any changes to my Xconfig settings when this occurred. I checked to make sure they were still in my registered hosts (they are), and that dtlogin is running on all of them (it is, one since before this issue arose, one was recently restarted when the server was bounced, and the third server's been up for 360 days, but the dtlogin was restarted about 2 weeks ago). I have viewed the /var/dt/Xerrors file, but am not sure what the messages mean.
I do not currently know if there is a firewall set up between my PC and the servers, although I suspect there is one. However, if something on that recently changed, I would think it would have caused an issue with all 4 hosts, not 3 of them. How do I determine if there is a firewall that is causing the problem? I can successfully telnet to the other servers, either from starting Xmanager to the one server which I can see in the broadcast, or through start-->run-->telnet.
I have tried making other changes in Xconfig on the XDM tab, but nothing has worked.
Thanks.
