Active Directory (AD) management is indeed a vast topic, and administrators often spend a significant amount of their time working with it. In an Active Directory environment, there are several essential tasks and concepts that IT support specialists, system administrators, and domain administrators need to understand. Here are some key points related to Active Directory management:
Default User Account and Groups:
- When an Active Directory domain is initially set up, it contains a default user account named "Administrator" and several default user groups.
- These groups have predefined roles and permissions within the domain.
Important User Groups:
- Domain Admins:
- Members of this group are administrators of the Active Directory domain.
- They have broad privileges to make changes to the domain's configuration.
- Domain Admins can also become local administrators on computers joined to the domain, granting them significant control.
- Enterprise Admins:
- Enterprise Admins are administrators of the Active Directory domain and have the authority to make changes that affect multiple domains in a multi-domain forest.
- This group is typically used in scenarios like upgrading the Active Directory forest to a new version.
- Domain Users:
- This group includes every user account in the domain.
- It can be used to grant access to network resources to all domain users without individually specifying each user account.
- Domain Computers:
- This group contains computer accounts for all machines joined to the domain (excluding domain controllers).
- Domain Controllers:
- This group includes all domain controllers in the domain.
Use of Domain Admin and Enterprise Admin Accounts:
- Domain Admin and Enterprise Admin accounts are highly privileged and should be used with caution. They are typically reserved for specific administrative tasks that require elevated permissions within Active Directory.
- It's crucial to avoid using Domain Admin or Enterprise Admin accounts for day-to-day tasks or as regular user accounts.
- These accounts have the potential to make significant changes across the entire organization, and using them casually can lead to unintended consequences.
Normal User Account vs. Administrative Account:
- As an IT support specialist or system administrator, it's recommended to have two separate accounts: a normal user account for day-to-day tasks and a separate administrative account for making changes to Active Directory.
- The administrative account should only be used when actively performing administrative tasks in Active Directory. Using a standard user account for regular tasks helps reduce the risk of accidental changes to the directory.
Delegation of Permissions:
- Delegation allows administrators to assign specific permissions to users or groups on Active Directory objects. This enables users to perform certain administrative tasks without needing full administrative privileges.
- Delegation is useful when certain tasks need to be performed frequently by non-administrative staff members, such as resetting passwords or creating user accounts.
