Does anyone know what > might be going on here? I have seen no generic Windows/BSD TCP/IP interoperability problems for WFWG or Windows95. Perhaps it is related to your client/server software... can you describe you environment in more detail? I do know that there is a well known problem caused by Microsoft's TCP/IP listening to RIP responses (in violation of legal usage of the packets) and dropping connections based on this. That is, if there is a flakey network on your wire, it will cause the windows boxes to act flakey. The "fix" for this is to put a gateway box between the offending box and the Windows boxes so that they are not on the same logical subnet (since this will isolate them from the broadcasts). There is also a known problem with Windows NT boxes illegally generating RIP packets and causing other hosts to dump. This is fixed in the latest release of NT, or a patch is available through MSN. Have you recently added an NT machine to a previously functional network? If this doesn't help, try backing off to an older version of FreeBSD; if this helps, then you will be able to CVS diff to find the actual problem code.
