VPN not connecting with XP

[truckseller]

I'm out of patients!!!
I have a Cisco 3000 VPN router. Server is running NT 4.0. I can connect with my VPN setup with Windows 2000 machines. I am now trying to connect a XP machine. I receive an “Error 734 The PPP link control protocol was terminated” when it tries to verify username and password. I have the machine set up exactly like the 2000 machines. I am using an account that I know works. Any suggestions on what I am missing? Thanks.

Generally, this would indicate that the user/password that are being sent are not expected . . .

Most often overlooked items (and I'm not sure exactly where they are in XP as I don't have one of those in front of me, but they are there).

A) Include Windows logon domain (maybe an option tab?)

B) Require secured password (security tab?) This one is only a problem if the server isn't ready to handle it.

C) Negotiate multi-link for single link connections. (networking tab --> settings button?)

Because the layout is not exactly the same, it's really hard to make sure you have the same settings with two different versions of Windows. To further complicate matters, Microsoft deals with the options slightly differently on different versions, so something that works fine on one may be a problem on another.

Could be something different than these, as well. Hard to tell, but check those out, then enable logging on the server if you don't get any results. Only way to figure out why it is kicking -- even that doesn't work 100%. Sometimes you just have to guess.

To turn on logging, look at this:

The ppp.log file can get big real fast, so you will want to turn logging back off when you get it figured out. Post back if you need help with the log contents.

Good luck!

I've tried (a) (B) (C) of your sugestion both ways and in all combonations and nothing works.
What I'm wondering about is that when it fails under "info tab" it says to go to the "security tab" and under "validate my identity as follows" I should select "allow unsecured password". That option isn't there and I'm not sure I would want that antway. I enabled logging and in the file it only has one line "PPP Initialized successfully". So I'm still at a loss. Thanks for your ideas.
