XP/Pro TCP stack corrupted, what to do?

I have an XP/Pro laptop that can't talk TCP/IP. I know the hardware
is fine since I can boot Knoppix and everything works.

I call it stack corruption because I have tried the following
connection types and get consistent symptoms.

RJ45 directly to my DSL/PPPoE modem to my ISP.
RJ45 to a Linksys router conected to my ISP.
Phone jack via PPP dialup to my ISP.
WiFi via a PCMCIA card to various public hotspots
(All use DHCP unless I'm testing something specific.)

All the above worked before the failure and other PCs can communicate
via my Linksys router.

Symptoms:

I can get an IP connection and I get a good IP number and appropriate
DNS and gateway and mask numbers depending on where I am testing from
but afterwords no TCP applications can open any connections.

Event Viewer shows no errors.

Suggestions?

Al,

you could try an IP reset, as explained in
http://winhlp.com/wxnet.htm . Search for netsh.
