Same error here as well. I followed the HOWTO doc and even tried the XP SP2 Nat traversal registry key, still no go. Error 789.

Synopex-

I'm pretty sure the 789 Errors refer to a problem with the pre-shared key itself or NAT-T.

Check this article:
http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B818043

Perhaps you may find some more info there.

Is your client XP? XP SP2? Are they connecting from behind a firewall device? Is NAT-T enabled on that device as well as 'VPN pass-Through?' What is the MTU (1365) size set to on your firewall device?

When I ran into this issue sometime ago verifying these settings and re-entering the pre-shared key under the 'IPSEC Settings' of the security tab in my client connection properties fixed the problem.

Best Regards,

Hello people,

I was having the same problem in a Windows 2003 SP1.
To solve this, start/restart the “IPSEC Services”.

Good lock,

Yes, Josué , this is documented for Windows 2000 in the L2TP instructions (also available via a link in the User Portal). It's unfortunate that the document doesn't include your tip for XP and Server 2003; earlier versions did.

Thanks - Bob
