Create User Audit Report in WIN2k Svr

I’m trying to create a network access audit report in Win2k server, similar to the one you can get from Novell, that will show me all the groups and shares that a user has access to. Due to budget restraints I’m unable to get SMS or any other third party tools at this time. Any help would be greatly appreciated. I have hunted everywhere in Win2k server to no avail.
