VPN Error 691

[Alisha]

I have searched all over the Internet, unable to find anything to solve this
problem. When trying to connect to a PPTP VPN, I get a 691 error.
Username/password are fine, I can connect to the VPN on XP with no problem.
I'm guessing that the reason is the authentication, but I don't know what to
do to fix this.

The VPN server uses MS-CHAPv1 and 40-bit encryption.

If more information is needed, please let me know.

In most cases, VPN error 691 is security settings issue. Any errors in the
VPN server Event Viewer?

I don't have access to that unfortunately, because I work from home part-time
and I'm not sure that anyone at work would want to try to fix this for just
one person who uses Vista. And, they also don't have an IT person at this
time.

I will try to ask, but I can't say if they want to spend any time on this to
help me out. I will reply back with an answer if I can get it.

Thanks,
Alisha

Try also looking in your local event log... (Right Click on Computer
and select Manage). You may have a more detail error message logged
in the Applications or System Log...

 

[Alisha]

Thanks Jeffrey, but it tells me less than when the error shows up after
trying to connect.

CoID={9A171B52-48E9-4486-9D2C-3A515FA9EBAE}: The user pisrpls\Alisha dialed
a connection named mySmartSim which has failed. The error code returned on
failure is 691.

Just today I had access to connect to another VPN and it also gave me the
same error.

Do a simple test. Just turn off windows firewall and any third party
security software, then try the VPN. Can you do it?

I already tried that, it gave me the same error.

Is pisrpls the name of your computer, your home workgroup, the computer you
trying to connect to, or the domain you are trying to connect to?

 

[Alisha]

It's the name of my computer.

Is pisrpls the name of your computer, your home workgroup, the computer you
trying to connect to, or the domain you are trying to connect to?

 

[Kerry Brown]

You have to specify the name of the computer or the name of the domain with
your user name.

e.g. domain_name\user_name

or

computer_name\user_name

The user_name has to be a valid user account either in the domain or on the
computer you are connecting to. If you don't specify this Vista uses your
computer name as indicated in the error message. If you are connecting to
work it's most likely a domain.

 

[Alisha]

I did set the domain when logging in with the username and password by using
the domain text box below the password.

 

[Kerry Brown]

The error message indicated that your local computer account was used. Try
typing in the full user name as in domain\user. It may not be the problem
but it will force the right credentials to be used eliminating one possible
cause of the problem.

 

[Alisha]

I tried it just now, but it gave me the same error.

 

[Kerry Brown]

OK we know that's not the problem then. When you said you could connect from
an XP computer are the Vista and the XP computer both on the same network?
Does one use wireless and one wired? What security software is installed on
the Vista computer?

 

[Kerry Brown]

I just re-read all your posts and realised you are using MSChap V1. Vista
doesn't work with MSChap V1.

You could try setting the connection for Chap but I don't know if this will
work.

 

[Alisha]

Yeah, I had tried Chap, but it didn't work. I really wish this worked,
because it's a pain to have to run a virtual machine just so I can connect to
work. It would be nice if there was a way around this, because I know the VPN
server at work isn't going to be upgraded for just me.
