So much for that guess. That might mean that the Linux box is either
not responding to UDP/ICMP traceroute packets possibly because you
have some kind of misconfigured firewall (IPChains, IPFilters) running
on the Linux LAN port. Without detailed knowledge of the Linux
configuration I have no way to determine exactly what is happening.

Dumb questions:
Can the OSR5 box ping the W2K box by IP address?
Can it traceroute the W2K box by IP address?

The real mystery is why the W2K tracert works and the OSR5 traceroute
does not. One would therefore suspect the OSR5 box. However, there
is no guarantee that the OSR5 box uses exactly the same traceroute
mechanism as W2K.

I'm not sure what to do next. Packet sniffing is my favorite tool.
Without additional information (exact error messages, version numbers,
Linux incantation, IP addresses, etc), there's not much that I can do
from here. Sorry.
