The people who used to log onto the network via dial-up (just like our
normal internet customers) have never had an LMHosts file, whether they
were using NT4 or Win95. Client for MS Networks (Win95) handles this in
conjuction with a workgroup name matching the NT domain name for the
network. All employees can see the entire network with no problems when
their IP is in the same C-class as the IPs for the servers and other
workstations in the office. Once the dial-up IPs were changed to a
different C-class (dynamically assigned as always), no one could log onto
the network anymore.
TCP/IP is the only protocol in use.
