As far as Active Directory is concerned, computers are very similar
to users. In fact,
computer objects inherit
directly from the
user object class, which is used
to represent user accounts. That means
objects have all of the attributes of
and then some. Computers need to be represented in Active Directory
for many of the same reasons users do, including the need to access

To set up the secure channel, a computer has to present a password to a domain controller. The domain controller then verifies that password against the password stored in Active Directory with the computer’s account.
