Why is a domain better then a workgroup for yourt company? Work groups are a loosely con nected group of computers. They rely on each other for nothing, but they are there to share resources should the need arise. There is no centralized management and so there is a low barrier to use. By default, Windows XP is in this mode.

Domains, on the other hand, provide centralized management and security. User access is controlled from a separate server called a domain controller and there is a “trust” built between systems in a domain. There are much more robust differences as well. A domain is a trusted group of computers that share security, access control and have data passed down from a centralized domain controller server or servers. Domain Controllers handle all aspects of granting users permission to login. They are the gatekeeper. In addition, most modern domains use Active Directory which allows and even more centralized point for software distribution, user management and computer controls.
