NT 4.0 and Server 2003 network configuration problems

Hello,

I have an NT 4.0 PDC with two NICs in it. Each NIC is on a different
network. One of the networks the PDC is in control of, there is no DHCP
set up on the network the PDC controls, and all the addressing is done
statically. On the network that the NT 4.0 PDC controls there are also
about 20 point of sale Linux machines. The other side is a server 2003
network and there is a DHCP pool for some machines. However, some
things are static including the PDC of the NT 4.0 network.

Here is my problem when ever I need to log into the POS Linux machines
from my desk which is on the Server 2003 network. I have to use a
persistence route that I set up on my desktop to see any computers on
the NT 4.0 network. I thought setting up a route to this network would
allow me to see everything on the NT 4.0 network, but it does not. I
can not directly log into the Linux POS machines. I can only see
computers that the NT 4.0 PDC is aware of in its windows networking
settings. As a work around I can log into any machine the NT 4.0 PDC is
aware of, then log into the Lunix machines from that computer.

Why is this, and is there anyway I can change this so I can log into
the POS Linux machines directly from the server 2003 network?

Thanks,
