How enable L2TP VPN for windows 2003 server?

[guest]

There are a number of details for configuring L2TP/IPSec. Without more
information, a very basic\short description would be:

- Under Routing and Remote Access, go to "Ports" to confirm that there
are L2TP ports configured (this is dependent on how you originally
setup Routing and Remote Access)
- On the client side, create a new VPN connection from "Network
Connections"

If you want to use IPSec on the L2TP connection, you have two options,
certificates or pre-shared keys. Certificates are more secure, but
require more setup where as pre-shared keys are less secure, but are
easier to setup, it all depends on your remote access needs. Below are
the instructions for setting up pre-shared keys:

How to Configure a Preshared Key on a VPN Client

1. In Control Panel, double-click Network Connections.
2. Under the Virtual Private Network section, right-click the
connection for which you want to use a preshared key, and then click
Properties.
3. Click the Security tab.
4. Click IPSec Settings.
NOTE: IPSec Settings may be shaded if on the Networking tab, Type of
VPN is set to PPTP VPN. A preshared key can only be configured if this
option is set to L2TP IPSec VPN or Automatic.
5. Click to select the Use preshared key for authentication check box.
6. In the Key box, type the preshared key value. This value must match
the preshared key value that is entered on the VPN-based server.
7. Click OK two times.

How to Configure a Preshared Key on a VPN Server

1. Start the Routing and Remote Access snap-in. To do this, click
Start, point to Administrative Tools, and then click Routing and
Remote Access.
2. Right-click the server that you will configure with the preshared
key, and then click Properties.
3. Click Security.
4. Click to select the Allow Custom IPSec Policy for L2TP connection
check box.
5. In the Preshared key box, type the preshared key value. This value
must match the preshared key value entered on the VPN-based client.
6. Click OK.

There are a number of other considerations you want to think about,
i.e. firewall rules, remote access policies, etc. but this was as
short of a description as I could provide.

Hope this helps.
