Windows ME and routing

Hello,

I am working on a Windows ME machine which is on a network
with a Windows 2000 server. The server runs DHCP, DNS and
a few other services. The client can connect to the
server, and can refresh DHCP leases, but I can't ever get
a connection through the gateway. What makes this weird is
that I have two other ME machines which are on this same
network, and both work fine using the exact same setup. I
have reinstalled ME from a formatted drive, and I get the
same behavior. Any clues would be much appreciated. Thanks.
