How many ways do you have to determine whether a computer is Domain

There are several ways to determine
1) On log on Windows dialogue box see whether the log on field has this computer
option or not. If it contains only domain names then it is a Domain Controller, if it
contains this computer option then it is either Work station or Member server.
2) Start -> Run ->Type netdom query fsmo -> The computer names that have been
listed there are Domain Controller.
3) Search for NTDS and Sysvol folder in system directory, if they are there then it is a
Domain Controller.
4) Start->Run ->Regedit32 ->Search for NTDS folder in HKEY_LOCALMACHINE
If you find that one then it is a Domain Controller.
5) Start -> Programs ->Administrative tools -> Active Directory Users and Computers
-> Click on Domain Controller OU -> the names that are listed there are the names
of the domain controllers.
6) In 2000 you cannot change the name of the Domain Controller so Right click on My
computer ->Properties ->Network Identification -> There Change button is grayed
out.
