Home Basic - VPN 691 error

Posted: 01-13-2009, 08:08 PM
I have a laptop running Vista Home Basic trying to create a PPTP VPN to a
Firebox 700 firewall. Every attempt to connect results in a 691 error -
username or password not valid. There are a number of computers running XP
and one running Vista Ultimate that have no problem creating the VPN. Does
anyone know of a reason that Home Basic can't/won't connect?

In most cases, VPN 691 is security issue. Have you tried different username?
Or this search result may help.

Yes, I have tried several usernames/passwords which I know are valid on the
firewall. I've also done a number of searches but haven't turned up anything
useful yet.

I'm not familiar with that particular device, but some use the NTLM protocol
for PPTP VPN authentication and have a problem with NTLMv2 by default used
in Vista. The following registry change may help.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\Lsa\LMCompatibilityLevel

If the key doesn't already exist, create a DWORD value named
LmCompatibilityLevel and set the value to 1,

OR save the following lines to .reg files and run it.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Lsa]
"LmCompatibilityLevel"=dword:00000001

This post may help too.
Solved: Vista VPN error 691
