Domain User Definition
Setting up a domain may also block outside traffic from accessing computers within the network which adds an extra level of security.
Domain user definition. For example a company may require all local computers to be networked within the same domain so that each computer can be seen from other computers within the domain or located from a central server. In a domain environment the administrator account and all new user accounts are automatically included as members of this group. A domain is also used to assign specific resource privileges such as user accounts.
While a normal domain user might look like domain username a managed service account will look like domain username. Thus a domain is used to manage all user functions including username password and shared system resource authentication and access. A domain has a domain controller that governs all basic domain functions and manages network security.
A domain contains a group of computers that can be accessed and administered with a common set of rules. Managed service accounts are created within active directory just like any other user account with the exception of having a dollar sign placed after the username.
