PPTP connections fail after XP SP2

[James Minard]

I have several PPTP connections that prior to XP SP2 were working just fine.
Now, all I get is a generic "Error 800: Unable to establish the VPN
connection. The VPN server may be unreachable, or security parameters may
not be configured properly for this connection." If I go to an non-SP2 XP
machine or a Windows 2000 machine on my network, I can connect just fine
using all the same settings. Anyone else have an experience like this, and
if so, have you been able to resolve it?

Configure the firewall to let the traffic through or if you are behind
another firewall, disable the XPSP2 firewall.

Sorry, I should have stated that I have already tried disabling the XP
firewall, and that did not change anything...

I'm having the same issue. No solution as yet I'm afraid, you?!

Me too. I can not find anything on this anywhere. I do find alot of people
with the same issue though, but no fix.

My gut reaction is turn off the built in XP firewall. Firewall is ON after
doing svc pack 2. This has caused us a ton of problems.

Since I have my workstation behind a firewall appliance (a router would
suffice) I do not utilize the SP2 Firewall at all. I have the service
set to disabled. I have 83 PPTP Connections Setup in my network and have
no problem connecting to any of them.
