Re: Weird PPTP state on XP after Ghost restore

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

hi Phil,

are you using simple PPTP or L2TP VPN ?

The IPSEC behavior has changed on XP SP2 and if you want to connect to
a L2TP VPN behind a Nat you have to do some tweaking on the registry

So here goes. I got a new Dell Laptop. I had a ghost of my old system. I
basically restored the ghost image onto the new system. Everything seems to
work fine. I have been using it for months. Then I tried to connect to a
PPTP server while on travel. Would not connect. I fired up my trusty VMware
session and a Windows XP client, and connected with NO problem.

My PPTP server sits behind a 1:1 NAT. If I plug into the hub on the private
network of the PPT server (i.e., we are on the same subnet), then my system
WILL connect to the PPTP server. I have tried to reset winsock and
everything else. I do not want to re-install the OS.

When trying to connect. I do see checksum errors (on packets sent from my
system) and TCP retransmissions in Wireshark. Seems like it sits in a
"Start-Control-Connection-Request" "Start-Control-Connection-Reply" loop
until a timeout occurs.

Does anyone have any pointers as to how I can try to debug this. All other
networking things appear to work fine.

Any pointers are appreciated.

Phil
