We are having a communication gap here. I assume your w2k client was
configured by right clicking on the Network icon and choosing
properties and then creating a dial-up connection. Normally this method
is using ppp communication from the w2k machine. Therefore it better be
using ppp on the side. So if you are not using AutoPPP you are not
starting a ppp connection. When mgetty starts pppd it is running as root
so pppd runs. Now is more usual to use pap authentication so you don't
need to type your usr-id and passwd to the server.

dns servers do not supply gateway information they just supply ip addresses
for machine names. You probably mean dhcp servers which do.
ppp gateway information is supplied by the client and
it is the address of the server. I can't right now check my w2k machine
but client configuration must supply the gateway information explicitly
or implicitly.
