Question : IBM ThinkCenter laptop suddenly canont access the Internet either Wired or Wirelessly

She is running XP.
INternet was working fine.  It suddenly turned off about 5 days ago.  There may have been a Windows Update at that time.  She Is running SP3.
I expect my question description incomplete.  I don't know where to start.  I expect you to ask me more questions about the situation.  Here's what I know.
Someone called me and said their Internet wasn't working.  I went over there.  I brought MY laptop.  I pulled the Ethernet cable out of her PC and plugged it into my PC.  It worked FINE - I was able to access the Internet fine.  I also saw many Wireless networks but I didn't try any.
I puit the cable back in her PC and I couldn't access the Internet.  I shut down both firewalls - both Norton 360 and the build-in Windows XP firewall.
She has FIOS although I'm not sure that matters since my computer worked.
When I do IP config, it just prints "Windows IP Configuration" and returns to the prompt.
Now ... this ThinkPad has this "radio" control which is related to wireless.  It shows Radio Off.  There is a button that says "Turn Radio On."  I click the button and nothing happens.

I apologize for the unclear statement of the problem.  I expect you will have questions for me to answer.  I am currently imaging the PC - just to be safe.  When the imaging is done, I will try a PCMCIA card - see if that works.

Regarding resetting the network stack:

netsh int ip reset resetlog.txt

but you might want to review this page first to see what the command does::

Regarding Restoration, on our Thinkpads, the Recovery Partition is accessed using F11 at boot time.  But realize that this option can wipe out the entire primary partition (system)..  be sure you BACKUP your user's data before you go this route.
