Active Directory is a structure supported by Windows 2000 or Higher operation systems that lets any object on a network be tracked and located. You can say its a database that holds information about component locations, users, groups, passwords, security, and other COM information. Some of this information is currently stored in the Registry (in win95, win98), but eventually (with Windows 2000) be moved to the Active Directory.

By default, Active Directory is located in the directory  \WINNT\NTDS\.  However, you can designate a different location when you promote a server to a domain controller.

Thanks for your reply...By default all the UserName and Password's are stored in the Active Directory ? Otherwise is it necessaary to set the UserName and Password explicitly ? It it is necessary then how we can assign UserNames and Passwords to it ?
