Lost Internet Connectivity after VPN Crash

D

Don

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).

I've completely reinstalled XP and the problem persists.

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!

I have some more information about this problem...

In the process of running the netdiag program, I was faced with trying
to post the results of the utility (since they were rather verbose).
In order to move this data from the "bad" machine to my "good" machine
I could not use a floppy since the "bad" machine does not have a floppy
drive.

What I wound up doing was creating a shared folder on the "good"
machine and mapping it on the "bad" machine and that worked. I am able
to map network drives that exist on the "good" machine onto the "bad"
one. The reverse does not work though. I cannot create a shared
folder on the "bad" machine and map it on the "good" one. When I try
to map a folder this way, the "good" machine sees the "bad" machine's
name as part of my local network but it cannot see anything inside the
machine.

The second point I wanted to make is that I noticed that there is a
difference between the two machines if I open the "Network Connections"
dialog box from the Start/Settings menu. On my "good" machine and on
my office machine, there is only one bold heading in this box labeled
"LAN or High Speed Internet". On my "bad" machine, there is an
additional heading labeled "Internet Gateway". This heading has one
entry under it which reads "Internet Connection" with type "Internet
Gateway", status "Connected", and name "Internet Connection".

Trying to bring up the properties window on this connection results in
a dialog box that does not have any useful information in it. Right
clicking on it and asking for it's status brings up a dialog box that
indicates that the connection is good and working fine and there is
constant send and receive traffic on the interface (not a large amount
but the counters do constantly increment). There is a "disable" button
on this form but pressing it does not appear to do anything - The
status display stays the same even though it takes about 30 seconds for
it to come back from the button press.
