Hi,

Can I get help on how to setup the following configuration:

Windows 2003 Server DC, Global Catalog, RRAS - single network.
VPN Server, AD Certificate Server. I want to set it up as a VPN
server. Note this is a single server with a single network card.

I have got it to work fine with PPTP.

However if I try to use L2TP then I get problems of missing a certificate
I have gone in and trying using the downloading the certificate to the
PC - http://<IPADDr>/Certserv etc. So the certificate is installed
on the client PC. However I don't know if I have to create custom
certificates on each side etc.

What am I missing - what steps have I not done correctly. (I think I am
close :)

Thanks,

Ward.
 
Sharoon,

Thanks for your help. Here is the error I get:

Error Connection to L2TP

Connecting to 10.100.1.1...

Error 781: The connection requires a certificate, and no valid certificate
was found...

So do I need to use IAS or Radius?

Thanks,

Ward.

You need machine certificates on both the Client and the RRAS Server for
L2TP.
If your RRAS server is on the domain, it would have already obtained the
required certificate.

On the Client side, can you confirm if the certificate is on the "Machine
store" and not in the "User store".

To check that, follow these steps:

On the command prompt, type "mmc"
File -> Add/ Remove Snap-in
Add
Certificates
Computer Account
Local Computer
Finish -> Close -> Ok

Expand the pane and confirm that the cert is present in the personal store.
