What is Active Directory ? Active Directory (AD) is Microsoft's directory service used to Manage below Network objects and Resources Manage users Manage Computers Manage Groups Control access to resources apply security policies     We can call AD as : A centralized brain of windows network Without AD: Every computer has its own users Passwords aren't Shared Policies must be configured one-by-one. With AD: one login works everywhere. Permission are controlled centrally. Security is enforced automatically. Active Directory Web Services Port number : 9389 Why Active Directory Exists ? Imagine a company having 1000 Employees: Without AD 1000 local accounts per Server. Manual access control. No central security. Difficult to Manage. With AD: One user account per employee login from any company PC Central password rules Easy onboarding or Offboarding Core Components of Active Directory ?

1) What is active directory? Active directory authorizes and authenticates all users and computers in a window domain network, ensuring the security of the computer and software. Through active directory various functions can be managed like creating admin users, connecting to printers or external hard drives.   2) What is DHCP and what it is used for? DHCP stands for dynamic host configuration protocol. It is used to allocate IP addresses to a large number of the computer system in a network.   It helps in managing the large number of IPs very easily.   3) What is scope and super scope? Scope consists of an IP address like gateway IP, subnet mask, DNS server IP. It can be used to communicate with the other PCs in the network. The super scope becomes when you combine two or more scopes together.   4) What is DNS? DNS mean Domain Naming Service, and it is used for resolving IP addresses to name and names to IP address. DNS is like a translator for ...
