Hello Damal,  Would like to give some input to your  query hope it will help.   Authenticated Users encompasses all users who have logged in with a username and password. Everyone encompasses all users who have logged in with a password as well as built-in, non-password protected accounts such as Guest and LOCAL_SERVICE. Domain User A domain user account enables the service to take full advantage of the service security features of Windows and Microsoft Active Directory Domain Services. The service has whatever local and network access is granted to the account, or to any groups of which the account is a member. The service can support Kerberos mutual authentication. The advantage of using a domain user account is that the service's actions are limited by the access rights and privileges associated with the account. Unlike a LocalSystem service, bugs in a user-account service cannot damage the system. If the service is compromised by a security attack, the damage is limited to the operations that the system allows the user account to perform. At the same time, clients running at varying privilege levels can connect to the service, which enables the service to impersonate a client to perform sensitive operations.
