Can someone help me please?

I have two laptops both running Windows XP with SP2.

On the first laptop, I have a PPTP VPN configured which works
perfectly.

On the second laptop, I have the same PPTP VPN configured with exactly
the same settings but I receive 'Error 651: - The modem (or other
connecting device) has reported an error' every time I try to connect.

I am using the same username and same password. I am connecting from
the same place to the same place.

I think I can make the assumption that the issue is with the second
laptop but any advise as to where to begin troubleshooting would be
very much appreciated. Thank you in advance.
