Logon Script

Hi, I have a quistion regarding logon script on a MacOS X. We have choosen to integrate our MAc's with ADmitMac...and it seams to work fine. Our Mac's can be integrated in our Active Directory and the users are able to logon with there W2K username/password. But...the next step would be to create a logon script placed on our W2K DFS - just like we do it for our PC users. A logon Script that automatic maps the server shares - dependent on the groups the users are belonging to in the AD. Does anyone know if this is possible on a Mac ??? If so...where can I get help/info. Thanks Thomas
