I'm in some dire need for suggestions on this issue I'm having. Background, I have 4 AD sites with 5 domain controllers (2003/2008/2008/2008R2/2008R2). I am trying to add a local administrator to the DC at each particular site (onsite IT guy) by using "control userpasswords2", then adding them to the BUILTIN administrators group. Here is the issue, on ALL of the Windows 2008/2008 R2 servers the prompt hangs after entering the group to which the new user should be added. The Windows 2003 server seems just fine. It seems that it has to do with the AD that is causing the issue, 2 of these servers are literally brand new/fresh install of 2008.
Event log gives no real information beyond application hang on netplwiz.exe.
