CREATING A PASSWORD RESET DISK ON A COMPUTER THAT IS A MEMBER OF A WOR...

Key Points

The new Windows Firewall policy performs packet filtering during Windows

startup, meaning that connections are protected from the moment they become

active on the network.

You can designate only a computer running Microsoft Windows 2000 Server or

Windows Server 2003 as a domain controller. If all computers on the network are

running Windows XP Professional, the only type of network available is a work-

group.

Key Terms

access token An object that describes the security context for a user. When a user

logs on, Windows verifies the user’s credentials. After the user is authenticated,

Windows assigns an access token that defines the user’s rights and permissions.

Active Directory A directory structure that allows any object on a network to be

tracked and located. Active Directory is the directory service used in Windows

2000 Server and Windows Server 2003. Active Directory provides the foundation

for Windows-based distributed networks.

Automatic Updates A Windows service that scans for, downloads, and installs avail-

able updates for Windows XP and other Microsoft programs.

domain A group of computers that consists of servers that maintain centralized secu-

rity and directory structures, and workstations that participate in those structures.

domain controller A server in an Active Directory domain that stores a copy of the

Active Directory database and runs the Active Directory service.

member server A server that is a member of an Active Directory domain but is not

a domain controller.

password reset disk A disk that allows a user to recover a user account when the

user forgets her password.

Secondary Logon service A service that allows a user to run a program (by using

the Run As command) with credentials different from the currently logged-on

user.

Security Center A software interface that provides at-a-glance security status for a

computer, including information on Windows Firewall, Automatic Updates, and

antivirus software.

stand-alone server A computer running Windows Server 2003 or Windows 2000

Server that is a member of a workgroup.
