Your callers need an LMHOSTS file setup correctly so they can find the PDC
and other computers on your network. If you were also running NetBEUI (and
all you dialup clients were running NetBEUI), you wouldn't be having this
problem. But, since you are only running TCP/IP (which is what you should
be doing because NetBEUI generates a hugh amount of spurious network
traffic), that means that NetBIOS has to run across TCP/IP. The NetBIOS
traffic can't find the PDC on the other subnet without some help from an
LMHOSTS file. Be sure and configure the dialup clients to enable LMHOSTS
lookups. It would also help of the computers on your network were also
using LMHOSTS files.
