Cannot create an additional Domain

June 20, 2010 at 07:24:05
Specs: Windows Server 2003
After creating the first domain, I intended to create a child domain (or an additional domain) but Windows requires me to DELETE the newly created domain. Is there any way to create the additional domain without deleting the newly created domain? Thanks all.

You certainly can create a domain which is a child of another. But what you cannot do is create them both on the same computer. One computer cannot be a DC for more than one domain. You can run a virtual machine such as with VirtualPC and create a DC for a different domain on it. From a licensing standpoint they are different computers.

This has to be done on a separate Domain Controller on the network from the one that host the parent domain:

1. Click Start, click Run, type dcpromo and click OK to start the Active Directory Installation Wizard and click Next on the welcome screen.
2. On the Operating System Compatibility page, read the information and then click Next. If this is the first time you have installed Active Directory on a server running Windows Server 2003, click Compatibility Help for more information.
3. On the Domain Controller Type page, click Domain controller for a new domain, and then click Next.
4 .On the Create New Domain page, click Child domain in an existing domain tree, and then click Next.
5. On the Network Credentials page, type the user name, password, and user domain of the user account you want to use for this operation, and then click Next. The user account must be a member of the Enterprise Admins group.
6. On the Child Domain Installation page, verify the parent domain and type the new child domain name, and then click Next.
7. On the NetBIOS Domain Name page, verify the NetBIOS name, and click Next.
8. On the Database and Log Folders page, type the location in which you want to install the database and log folders, or click Browse to choose a location, and then click Next.
9. On the Shared System Volume page, type the location in which you want to install the Sysvol folder, or click Browse to choose a location, and then click Next. The Sysvol folder must be located on an NTFS volume.
10. On the DNS Registration Diagnostics page, verify the DNS configuration settings are accurate, and then click Next.
11. On the Permissions page, select one of the following:
 Permissions compatible with pre-Windows 2000 server operating systems
 Permissions compatible only with Windows 2000 or Windows Server 2003 operating systems.
12. On the Directory Services Restore Mode Administrator Password page, type and confirm the password that you want to assign to the Administrator account for this server, and then click Next. Use this password when starting the computer in Directory Services Restore Mode.
13. Review the Summary page, and then click Next to begin the installation.
14. Restart the computer.
