Strong Password of your Administrator like “Pa$$w0rd”.

Install Microsoft Windows Server 2016 on your machine. NTDS.DIT is a database file (New Technology Directory Services Directory Information Tree)Ĭentralized authentication through Kerberos protocol In Domain our Domain is AD DS (Active Directory Domain Services) every user will authenticate form it. We also can install Windows Updates to our clients from our Windows Server thought WSUS (Windows Server Update We can implement Group Policies or Security Permission from the Server. Password of any user just right click on user and click on reset password. If we have to create 400 users we can create in seconds. We create users on Windows Server and login it anywhere in the network. Now all systems will authenticate from it. DomainĪs you can see we put a Server place of a system. It has Decentralized Database, Authentication separately, are all independent systems. NTLM protocol use for authentication in workgroup (New Technology LAN Manager) In workgroup our password will save in SAM file (Security Account Manager) We have to go physically to all single system and do required task. If we have to implement Group Policy no our systems, implement some security permissions,Īnd install some windows updates. Mean to say we create only users in 2 days. Then the total creation time will be 8 hours and 20 minutes and our job time is 7 hours.

We spouse 1 user creation time is 1 minute. But if we have a network of 400 users and

If any credentials are incorrect then login access will be denied. Whole systems, will have to login after authenticate from this database. If we create a shared folder on System4, in which our database will store. But if our System1 down or any disaster occur. Then we shall be able to login at that systems. If we want to logon at that systems then weĪlso have to create user with the name of 'Cortana'.

Now, if Cortana wants to logon on System2 or any other system except System1. We create a user on System1 with the name of 'Cortana'. We know if we have to use system or computer then we must have a user with any Any system can independently do any task, what ever he/ she wants. As showing in Figure 1.1 we have a bus-topology and 8 computers are connected with it through a T connector.
