These are broadcasts that are supposed to happen on the local network only. Make sure the IP address and netmask of the Win98 machines matches what the LANModem thinks the local network ought to be. For example, if the Win98 machine has: Address: 192.168.100.100 Netmask: 255.255.0.0 And the LANModem (never worked with them, may look different, but you should get the idea) has: Address: 192.168.100.101 Netmask: 255.255.255.0 then it might dial out to route the broadcasts by the Win98 machine, because they are outside what it thinks the local net ought to be. This is especially tricky because some equipment do their addresses like: a.b.c.d/y where y is the number of bits used for the network part of the address; i.e., as another way of showing you the netmask. You can use tcpdump if you have it to help you see what's really going on.
I've got a W98/Samba LAN running with a 3Com OfficeConnect LANModem for shared internet access. Periodically, like every 10 minutes, it dials out, due to a DNS request for the workgroup/domain (same) name. Any fix for this? Can I just put a dummy address in all the host files?

A PC is doing a _DNS lookup_ for the workgroup name, this I know from the logs on the modem. Any way to keep a W98 machine from doing DNS lookups for its workgroup name, or to fool it into thinking that it knows the IP address?
