I'm running SME7.3 as server and gateway and everything. I have two machines plus the server on a single switch as a small LAN. On both client machines I can ping and access the server (via browser and My Network Places) just fine. However, one either client machine, I am unable to ping or connect to the other client machine. When I try and ping the other it comes up with "Request timed out" but it did resolve the hostname correctly. On the server I can ping both client machines by IP just fine (but not by hostname, that's a separate problem I suppose).
I have both client machines set up the same as far as the LAN adapters and protocols being used are concerned. Changing the NetBIOS settings around on both have not worked either, as well as trying to disable File and Print Sharing service under the LAN adapter properties.
I've spent several hours googling, pulling hair out, and trying everything I can think of but nothing thus far has solved this issue. Searching on the forum here didn't lead to any solutions, most of the results I came up with were related to VPN situations.
EDIT: I'm not sure if it's a subnet problem or not exactly but, the one client's IP is 192.168.14.254 and the other's is 192.168.13.255. Both have subnet set to 255.255.240.0. The server's IP is 192.168.1.1.
EDIT 2: Both client machines are running Windows 2000 Professional with SP4 installed and neither have any kind of firewall or antivirus or similar security software installed.
