PLEASE HELP!!! - ERROR 651 IS KILLING ME...

R

Rafael

Hello.

I have a Dell Latitude laptop running Windows XP with Service Pack 2.
I have broadband and am connected to a wireless network.

I am trying to set up a PPTP VPN connection which terminates on a
Cisco 831 router - a task which I have completed successfully on many
occasions, also with machines running Windows XP Pro, and connecting
to the same Cisco 831 router. For this reason, I cannot believe that
it is a problem relating to the Cisco 831 router directly, or with
port 1723.

Each and every time I ty to connect with this particular laptop
though, I get the "Error 651 - The modem (or other connecting device)
has reported an error."

If I change the type of VPN from 'PPTP' to 'Automatic', I receive
"Error 800" instead ("Unable to establish the VPN connection. The VPN
server may be unreachable...").

I have a second laptop currently on the same wireless network which
works perfectly with exactly the same PPTP VPN connection so the
problem must be with the laptop itself surely? I have also confirmed
that my network will permit multiple outgoing PPTP connections but I
receive the error even when there are no other connections in place
anyway.
From a great many hours spent scouring the Internet, I can see that
this is a known problem but I cannot for the life of me find a
solution.

I seem to come across many registry cleaners that say they will rid me
of these errors - are they worth the money? Is it likely to work?

If anyone has any suggestions, I will be eternally grateful as this is
driving me insane.

Thank you in advance.

Remove/uninstall the Modem and its driver, run disk cleanup an defrag in
safe mode, then open this command and type in:
sfc /scannow click [OK] you will need the XP CD installation media for this
operation to accomplish.

CAUSE
This problem occurs because the Layer 2 Tunneling Protocol (L2TP) tries to
create a host route and then detects that the route to the host that was
created by the dial-up connection already exists.
