No gateway - needi to repair network connection

I don't know if this is C32-related or not, but I'd appreciate opinions.
On just one workstation, just starting today, after a reboot, IPCONFIG
shows no gateway. 15 other workstations, and this one until today, all
worked fine. IPCONFIG /release, IPCONFIG /renew does _not_ fix the
problem, but telling XP to repair the connection does.

We use BM and the default gateway is on our BM server. The odd thing is
that Internet browsing works even without the gateway showing up because
we use a proxy at that same address, so the machine clearly can see that
address.

I'm clueless on this one. Our C32 is a late beta of 4.91 SP3, same on
all w/s.

Thanks in advance.

Sounds like a corrupted IP stack. Try sniffing the wire and see if this
information is being sent by the DHCP server and the client is not accepting it.

That symptom also happens to match what could be seen when the
ZENworks NOVDHCP issue existed. (Where NOVDHCP would open and then
never close the client-side DHCP port, thereby interfering with both
the Novell Client SLP driver & Windows itself from being able to use
the DHCP port to obtain configuration.)

In a LAN trace, another clue for that same issue is seeing a DHCP
Inform request for option 100 (the ZENworks Middletier default option,
also used for DHCP printing configuration). Seeing this request but
no other can also be a clue of NOVDHCP being an issue.

10093676: Error: "Tree or server not found" when SLP configured to
obtain DA addresses via DHCP.

The other condition that was cited when such a symptom was discussed
before was turning "portfast" or whatever "quick spanning tree bypass
mode" your switch vendor has. Wouldn't have been at the top of my
suspect list, but it is something that could have happened "even
though nothing changed at the workstation", for what it's worth.

Thanks, both. FWIW, we have never used Zen at all.

Also, if the issue is with the IP stack, would simply doing a complete
uninstall/reinstall be a possible solution to the problem?

Unlike previous Windows versions, removing TCP/IP from Control
Panel does not refresh the files. Files are refreshed only during
a service pack install or worst, reinstall the OS.


Take the packet trace and see what's going on in the wire.

OK, I will try to do that. I've got Ethereal floating around here and,
although I'm not great with it, I've used it two or three times now and will
see what I can figure out or at least post here.

One more question about a "blunt force" solution - the machine runs XP/SP2
and came from the factory w/ SP1, which means I could uninstall and
reinstall SP2 and all those post SP2 patches via Windows Update - does that
sound like a possible solution that's at least short of a full OS reinstall?

An update - yesterday, even rebooting the machine didn't fix the problem
because we still had to repair the LAN connection. Today, however, a reboot
worked fine - we have a gateway. I am going to hope this one stays fixed.
I'll report back if the status changes.
