Domain User Groups

Hi

Im currently working on a intranet and trying to set up some security. The intranet acesses a SQL server 2000 database. I would like to know if there is a stored procedure(or other way) of returning all the domain groups that a user belongs to when passed the users NT login. I found xp_enumgroups which returns all the groups on the domain and also xp_logininfo which returns the users of a passed domain group. These are usful but i need to just pass the NT username and return all the Domain Groups. Any thoughts, ideas would be great!

CheersI don't know of any way to do this using Microsoft supplied code in SQL Server. The code could certainly be written, but I think it is much easier to do at the client side than on the server.
