A Windows 95 client able to connect to shares in its own subnet with no problem. When it tries to connect to the WAN, the other clients are visible (sometimes) but no shares can be opened. All TCP/IP configs are fine and consistent with the others in that subnet (who are not experiencing these problems). Tried reinstalling the drivers of the NIC - no luck. Tried removing and replacing NIC and reconfigure all TCP/IP properties again.... still no luck. Any suggestions would be appreciated. TYIA.

a complete reinstallation of the OS is not an option.. there is an application on there that is mission critical that would be a pain to get license approval for if we had to reload it.

try changing the NIC altogether. Different brand, preferably better. If the NIC in the problem machine is different from the others, try changing to the model the others are using.
Don't forget to yank any drivers from the previous card. In fact, check first to make sure there are no driver "droppings" from any previous NICs in Device mgr (safe mode shows all sorts of leftover crap) or the network properties that could interfere with the present one.

Is there a firewall (or two) between the subnet with the Win98 machine and the remote site? If so, then perhaps the firewall is blocking TCP port 139 outbound requests from the IP address the Win98 machine is using?
Also, you said other machines from the Win98 subnet can access a share over the WAN. Are these other machines Win98, or another OS?
Also, a router access list could be blocking the port. Check that too.

The windows 95 computers can't read shares or anything on the network with words more then 8 characters. You could add another share and rename it with fewer characters. IE if you had a share called management add another share to the same place called manage or man. Also you may want to make sure netbiose is enabled.
