How do you verify whether the AD installation is proper?

To verify a proper Active Directory (AD) installation, you can use tools like the Active Directory Users and Computers (ADUC) console to check for the presence of necessary objects such as users, groups, and organizational units. Additionally, running the "dcdiag" command in Command Prompt can help diagnose any issues with domain controllers. Checking event logs for errors related to AD services and using "repadmin" to verify replication status are also effective methods to ensure the installation is functioning correctly.
