There should be a minimum of two DCs in a domain. If you only have one domain, all your DCs should also be GCs. How many DCs at each site will depend on what your requirements are. One DC at each site can service thousands of users with regard to authentication.

A network domain is an administrative grouping of multiple private computer networks or hosts within the same infrastructure. Domains can be identified using a domain name; domains which need to be accessible from the public Internet can be assigned a globally unique name within the Domain Name System (DNS).

Hi, In short, the settings you configured in the default domain policy would apply to all the computers in the domain. And the default domain controller policy settings would just apply on the domian controller servers within the domain. Also you can refer to the link provided by Sneff_Gabor.

How to determine which DC has the domain-specific FSMO roles, ie RID Master, PDC Emulator and Infrastructure Master. Open the Active Directory Users and Computers console, right-click the domain and then Operations Masters. Here, on each tab, you can see which Domain Controller has the above FSMO roles.

Domain names are used to identify one or more IP addresses. For example, the domain name microsoft.com represents about a dozen IP addresses. Domain names are used in URLs to identify particular Web pages. For example, in the URL http://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.com.

While longer than desirable, 27 characters (including .com) is not overly excessive, but yes, long domain names do affect user experience. Some more than others. 'Power users' know how to avoid typing the address if possible.

Domain users. A domain user is one whose username and password are stored on a domain controller rather than the computer the user is logging into. When you log in as a domain user, the computer asks the domain controller what privileges are assigned to you.

On environments with only one Active Directory (AD) server (domain controller), a change usually takes up to ~5 minutes to get processed and sent to the cloud, barring any issues in regards around network latency, processing and also the size of the organization being synchronized.

In a small environment, at least one domain controller (DC) should be a DNS server. It is possible to install DNS on servers which are not DCs, including non-Windows servers, but installing DNS on DCs allows the use of AD-integrated lookup zones (see below), which improve security and simplify zone replication.

The Domain is used to manage access to a set of network resources for a group of users (applications, printers, etc.). This information is stored in a master directory database which resides on a single Windows server on a network. This Windows server is designated as a Domain Controller.

Active directory is just like a database that stores information as object of users and computers. But Domain Controller (DC) is a server that runs Active Directory and use data stored on AD for authentication and authorization of users. Domain controller manages security policies of Window NT or Windows Server.

Ideally you should have a Domain Controller at each site so that users in that site can continue working if the intersite connections fail or if other sites go down. Having a domain controller in each site will also speed up logons at the site since authentication will not have to be done over the intersite connection.

AD Domains In Active Directory terms, a domain is an area of a network organized by a single authentication database. In other words, an Active Directory domain is essentially a logical grouping of objects on a network.
