Set up Active Directory right

Active Directory (AD) is Microsoft's directory service included in Windows 2000. AD installation is

a very complex task, even though it's set up through a simple wizard (Dcpromo.exe). However,

many experienced administrators don't trust wizards and try to do most tasks on their own.



DNS is a critical step in AD deployment; if it's not set up right, Active Directory won't work

correctly. While Dcpromo.exe can automatically install and configure the DNS server for you, it's

much better to do this step manually.



Follow these steps before installing Active Directory on the first computer:



Install and configure a DNS server on your network.

Test the DNS server and make sure it's working properly.

Configure the soon-to-be domain controller to use this DNS server.

On the DNS tab in the Advanced TCP/IP Settings dialog box, configure the correct DNS suffix for

the connection.

Again, make sure the computer can successfully use the DNS server.

Use Dcpromo.exe to install Active Directory.



Even though it's easy to use Dcpromo.exe and let the wizard do everything for you, it's much harder

to troubleshoot problems after the installation. Install and verify DNS before installing AD, and

you'll know that DNS is working correctly and that the cause of any problems lies elsewhere.
