If you're running under NT, NetUserGetGroups() and NetUserGetLocalGroups() seem ready-made for the task - it'll retreive the global and local Group memberships of a user respectively. You can also approach things from the other side, with NetGroupGetUsers() and NetLocalGroupGetMembers(), but again, they're implemented under NT and not under Win9x.

Paul-Vlad Tatavu sells an ActiveX control that might be helpful here; you also might want to investigate using the ADSI automation objects (Rick Strahl has sample code on his Web site showing how VFP can access some part of the ADSI functionality.)
