I am having problems configuring Windows 2003 server and Windows XP Pro SP2 client, to connect over VPN using EAP and L2TP
They are on the same LAN.
When connecting from client after about a minute I get:
In routing and remote access \server\properties\securit
If I choose windows authentication
I get error message:
Error 792: The L2TP connection attempt failed because security negotiation time out.
If I choose radius authentication
I get this error message:
Error 789: the l2tp connection attempt failed because the security layer encountered a processing error during initial negotiantions with the remote computer.
I have looked at MS knowledge base id:326751
Which suggests but says it not recommended:
1. Add the ProhibitIpSec registry value
2. Manually configure an IPSec policy on both the Windows 2000 Server-based computers
It says applies to Microsoft Windows 2000 Enterprise Edition x2
So, thats not me... right?
Do I really have to do all this or is there a more sutiable solution?
What is best, radius or windows authentication? I think windows is more suited for my needs, but whichever will work essentially.
