What exactly does a red 'X' in Active Directory represent? I know that a red 'X' over a user account means the account is disabled, but what does it represent when placed next to a Computer object?
It means the computer object is disabled. That would mean if the computer was switched on it would be denied access to the Domain.
Every computer running Windows NT,
Windows 2000, Windows XP, or a server
running Windows Server 2003 that joins
a domain has a computer account.
Similar to user accounts, computer
accounts provide a means for
authenticating and auditing computer
access to the network and to domain
resources. Each computer account must
be unique.
