<> What is domain?
A domain is a group of network resources like applications, printers and shared folders. To access those resources users need to use their assigned username and password. DNS is a server level service which we will have to install during active directory installation. It is very difficult for human being to remember different IP address but they can remember domain name easily. A Domain Name Service resolves domain name to IP and IP to domain name.

The SYSVOL is called the replication folder. It keeps all the public files of any domain. It replicates all policy and users level data after an interval.

The SYSVOL folder stores the server’s copy of the domain’s public files. It is used to deliver the policy and logon scripts to domain members. Moreover, it replicates file-based data among domain controllers. The Sysvol folder is shared on an NTFS volume on all the domain controllers in a particular domain. All active directory data base security related information store in SYSVOL folder and it’s only created on NTFS partition.

<>What is the Global Catalog?
The Global Catalog is a server that contains all of the information pertaining to objects within all domains in the Active Directory environment. It is something that each domain has, and it is used for authenticating the user on the network, on windows 2000 network logon’s were protected from failures by assigning a Global Catalog to every site. Global Catalog is a database which maintains the information about multiple domains with trust relationship agreement.

<>What is the use of Group Policy?
Group Policy is a feature of the Microsoft Windows NT family which gives you administrative control over users and computers in your network. It provides the working environment for server users and computers. In addition, it gives us the central management and configuration for windows operating systems and settings.
