Question - How do I use Registry keys to remove a user from a group?
Answer -
In Windows Server 2003, you can use the dsmod command-line utility with the -delmbr switch to remove a group member from the command line. You should also look into the freeware utilities available from www.joeware.net . ADFind and ADMod are indispensable tools in my arsenal when it comes to searching and modifying Active Directory.
