using IPSec on Cisco access server

[gentian_hila]

I have some users with Windows 2000 that dial in an access server Cisco 2620. But i see that some other people connect to my company network. I've changes several times the passwords of my clients but it seems that somehow they are stolen again. So i want to implement IPSec with a preshared key on Windows 2000 and Cisco access server. I use AAA method with Tacacs. I've configured Windows 2000 with a preshared key. I want to do it now on Cisco access server (i use a pool of dymanic IP addresses on RAS).

What should i do on the Access server

Any help or idea would be deeply appreciated.

Here is the link which explains how to configure Win2000 and Access Server for that

Now there is one other way to block the access to certain device for some users. You can download per-user based access-lists from AAA servers to permit/deny access to certain network devices.

Here is the url for sample config ton that too.
