How to install Active Directory on my Windows Server 2003 server

1. Right click My Computer and choose Properties.
2. Click the Computer Name tab, then Change.
3. Set the computer’s NetBIOS name. In Windows Server 2003, this CAN be changed after the computer has been promoted to Domain Controller.
4. Click More.
5. In the Primary DNS suffix of this computer box enter the would-be domain name. Make sure you got it right. No spelling mistakes, no “oh, I thought I did it right…”. Although the domain name CAN be changed after the computer has been promoted to Domain Controller, this is not a procedure that one should consider lightly, especially because on the possible consequences. Read more about it on my Windows 2003 Domain Rename Tool page.
