Have you tried BUILTIN/Adminstrators?

local machine


I am trying to determine is a user is a member of the
Administrators
group (so I know whether to add them or not), but I can't
seem to get it
working.

I'm using the following code:

           DirectoryEntry group;

            group = new
DirectoryEntry("WinNT://" +
Environment.MachineName+ "/" +
"Administrators");
            bool retVal =
(bool)group.Invoke("IsMember", new object[] {
"WinNT://" + Environment.MachineName +
"/" + userName });

retVal is always false.  I've tested for every user in the
group.

I am a local administrator.  Might I not have some
permission that I
need?

Thanks,
-Mont

If I use the path:
WintNT://MyComputer/BUILTIN/Administrators I get an
exception with I try and Invoke IsMember.  Without the
BUILTIN, no
exception, it just always fails.

Thanks,
