HELP: getting group information from win2k domain controller

I looked into the MSDN library and did not find a proper function to retrieve
nested group name.

I wrote a windows program using NetUserGetGroups and NetUserGetLocalGroups, and
neither of them
give me what I want. Since I am using 2 win2k machine, according to the trace,
underlying they are using
MS/DCE for these two functions. So I guess maybe I haven't found the right MS
API for this purpose.
Simply switching to DCE/RPC won't solve the problem.

I looked into all the Net* APIs and none of them looks good.

Does anyone happen to know the right way to retrieve the nested group list ? Or
if there is any function that
can check the parent group of a group ? That way we can do recursive search to
enumerate the whole list.
