You can use my Win32Admin.DLL ( http://home.comcast.net/~habullock/Win32Admin.htm#Group ) without installing ADSI on all those NT4 clients. Using a centrally executed Admin script, you can use:
GrpEnumMembers($Server, 'local', LocalAdminGrp($Server))
then loop through the result. Sample code is on the web site.
Program:Win32Admin3.zip (835K) Ver: 2.0.2.0 handles the results more gracefully. See the example code. Let me know if you have any questions.
