Authenticating remote users On Windows NT domain through ACS Server

[prufin]

I want to enable our remote dial-up users to open a windows session

on our NT domain witch is at the headquarter.

I don't use windows ras server.

The dial-up connections rely on the LETP Architecture of our Service Provider.

up now , the provider manage the triple AAA authentication.

I plan to set up an ACS server at the headquarter.

How should i do to manage this remote opening session

Thanks for help me

Can you clarify what you mean by opening a windows session? Do you simply want to authenticate using your Windows NT Domain? If you wanted to achieve this and you have an ACS server then you can simply ask the ISP to proxy the authentication requests to your ACS server for the authentication.
