Can't Ping My Own IP Address

Tech-Archive recommends: Fix windows errors by optimizing your registry

I'm running XP Pro with all the latest updates. I was running a VPN
client from my employer and when I disconnected the VPN, the client
crashed. Ever since then my Internet connectivity is VERY sporadic.
Applications like Firefox and Thunderbird will not talk to the net at
all getting a "connection refused by server" message. Outlook can
sometimes get out. IE is the only application that can get to the net
pretty consistently but even that is not 100%. Some pages won't come
up.

I've checked all hardware (D-Link router and cable modem) and
everything is fine. Another computer attached to the same router has
no problems (that's the machine I'm sending this from). That second
computer can ping it's own IP address with no problems and has no
trouble getting out to the Internet and this second machine can ping
the computer that is having the trouble.

I also tried connecting the VPN again and disconnecting it. It does
not successfully connect any more either and the disconnect does not
fix the problem. I also tried uninstalling and reinstalling the VPN -
Again with no effect.

I've tried running with the XP firewall disabled and enabled with no
change
in the symptoms.

I ran the XP Network Diagnostic tool and it failed. The only part of
the test that failed is when it tries to ping it's own IP address. I
tried this manually and got the same results. I can't ping my own IP
address. The "good" machine on the local network works fine and can
ping anything including the machine that is having the problem.

I'm guessing that the VPN crash left my machine in some indeterminate
state but I've checked everything I can think of and nothing appears to
be wrong.

Help!
