Firewall issues w/Winserver 2008 and FMS 10
Server System: Windows Server Standard, SP 1, Filemaker Server 10.
Client Systems: Windows XP, SP3, FMP 10 v2
The scope for each of these "exceptions" is "any computer".
When I first boot the server, I can open a hosted file from a client machine. After a few minutes pass, if I stop and restart the client FMP 10, or attempt to connect to the hosted files from a different client machine, the server has disappeared from the Hosts list. I can make the server reappear, by using the admin console to stop and restart the database server. I can also make the server reappear if I turn off the firewall on the server. In fact, if I leave the firewall turned off, the problem does not occur.
This suggests that server's firewall is not correctly configured.
Any guesses as to what I've done wrong?
