- The process of a user logging on to a domain-joined computer for the first time involves several steps. Let's go through the process in detail:
1. Computer Boot: When the computer starts up, it goes through its normal boot process, loading the operating system (e.g., Windows) and initializing network services.
2. Network Initialization: The computer connects to the network, either via a wired or wireless connection, and obtains an IP address. It also attempts to locate a Domain Controller (DC) to join the Active Directory domain.
3. Locating a Domain Controller: The computer uses DNS (Domain Name System) to query for the SRV (Service) records that indicate the locations of Domain Controllers in the domain. It typically looks for the _ldap._tcp.dc._msdcs.domain_name SRV record.
4. Domain Controller Communication: Once the computer has identified a Domain Controller, it establishes a connection to it using the Lightweight Directory Access Protocol (LDAP).
5. Computer Account Creation: The computer requests to join the Active Directory domain by sending a join request to the Domain Controller. The Domain Controller creates a computer account in the Active Directory database.
6. Secure Channel Establishment: The computer establishes a secure channel with the Domain Controller to ensure encrypted communication for future interactions.
7. Kerberos Authentication: After the computer account is created, the computer requests a Ticket Granting Ticket (TGT) from the Domain Controller. This involves the computer's security principal (Machine Account) authenticating to the Domain Controller using the Kerberos protocol.
8. Group Policy Processing: The computer receives and applies Group Policies associated with its location in the Active Directory hierarchy. Group Policies define various settings and configurations for the computer and user accounts.
9. User Logon: When a user attempts to log on to the computer for the first time, the computer sends the logon request to the Domain Controller.
10. User Account Verification: The Domain Controller verifies the user's credentials, ensuring that the username and password match those stored in the Active Directory database.
11. User Profile Creation: If it is the user's first logon to this particular computer, the system creates a local user profile for the user. This profile contains user-specific settings, preferences, and documents.
12. Logon Scripts and Policies: Logon scripts and policies assigned to the user are executed to configure the user's environment and apply specific settings.
13. Group Membership and Permissions: The user's group memberships and permissions are checked to determine their access rights on the local machine and in the network.
14. Desktop Initialization: The user's desktop environment is initialized, and the user gains access to the desktop and other resources based on their permissions.
15. Logon Completion: Once the login process is complete, the user can start using the computer and its associated resources within the domain.
It's important to note that subsequent logins on the same domain-joined computer will be faster due to the use of cached credentials and the established secure channel with the Domain Controller, which reduces the need to repeat some steps for authentication. Additionally, the specific login process may vary slightly depending on factors such as the operating system version, domain configuration, and network setup.
Very deep and informative concept.thanks for sharing for valuable knowledge
Thanks and welcome
Please correct me if I am wrong file share permissions are given to the user not computer
