Hi, I have just the OPPOSITE question: I installed Windows 2003 R2 from nLite customised CD, and it had Auto Logon ENABLED. Since it is Win 2003 server, I would like to remove this autologon feature. BUT there is no Winlogon enttry in Registry, neither is any user in "control userpasswords2" dialog window checked to logon automatically. Any idea where is it set to logon and how to remove automatic logon?
