Active Directory Groups with SQL Server 2005

Ok, so I already have an existing Active Directory connection on my server. I know the active directory query is working. What I want to do is query for all ou and / or groups in the active directory and also be able to find users belonging to those groups / ous.

this is the current query, which is just pulling in user information (or part of a stored procedure configured to pull all users):

SELECT
    userAccountControl,
    DisplayName AS [NAME],
    givenName AS FIRSTNAME,
    middleName, 
    sn AS LASTNAME,
    employeeID AS EMPID,
    telephoneNumber AS EXT,
    Title, 
    Department AS DEPT,
    Division,
    sAMAccountName AS UserName,
    mail AS Email,
    homeDirectory AS HomeDir,
    userPrincipalName AS LOGON,
    manager
FROM         OPENQUERY(ADSI, 
                      '
 select
     userAccountControl,
     DisplayName,
     givenName,
     middleName,
     sn,
     employeeID,
     telephoneNumber,
     Title,
     Department,
     Division,
     sAMAccountName,
     mail,
     homeDirectory,
     userPrincipalName,
     manager
 from ''LDAP://name''
 where sn > ''a''
    and sn <''h''
 order by DisplayName
 ')
