Urgent Networking Problem

[Zomoniac]

I have a laptop running XP, and it has wired and wireless, both worked
fine and connected to my home and office networks without a problem
yesterday. This morning I plugged it into my home router and had no
internet. I checked my network settings and I had been assigned a DHCP
from the router, and the router's address showed up in my network
settings as being the current gateway, but when I went to ping the
router it couldn't find it.

So I brought it into work, same thing happened. Connected the cable,
got a DHCP address with the router as a gateway (different IP ranges so
I know it changed), no internet, can't see any computers on the
network, can't ping the router, nothing at all. I've virus checked,
spyware checked, adware checked, restarted many times and nothing is
giving results. Any ideas anyone, this is really urgent!

Have you checked out all firewalling options and such? Possibly disabled
them for purposes of the test?

Try repairing the Windows XP TCP stack - visit
http://support.microsoft.com/default.aspx?scid=kb;en-us;299357 for help with
that.

On an aside - have you ever added any persistent routes to the machine?

It was a new version of Netscreen Remote. Nothing works when it's
installed. Take it off and everything's fine.
