Creating Additional Domain Controller for an Existing Domain

septiembre 16, 2013

In this article, we will install Additional Domain Controller in an existing Windows Server 2008 R2 domain.

1. You must have administrative credentials on the existing Active Directory domain to add an additional domain controller. You can configure the server as a member of a workgroup or as a member server within the existing domain. Here, I configure as a member server within the existing domain.
2. Click Start and then click Run. In the Run dialog box type dcpromo and then click OK.

3. The dcpromo command will automatically install the relevant files on the computer prior to beginning the domain controller promotion process. This dialog box will start checking if Active Directory Domain Services binaries are installed, then will start installing them.

4. On the Welcome To The Active Directory Domain Services Installation Wizard page, click Next.

5. On the Operating System Compatibility page, click Next

6. On the Choose a Deployment Configuration page, select Existing Forest and then select Add A Domain Controller To An Existing Domain, and then click Next.

7. On the Network Credentials page, click Next

8. On the Select a Domain page, Select a domain for this additional domain controller page, and then click Next

9. On the Select A Site page, select the site in which you want to locate the domain controller and then click Next

10. On the Additional Domain Controller Options page, select additional installation options for the domain controller and then click Next

11. On the Active Directory Domain Services Installation Wizard page, you can ignore this warning and click Yes to continue.

12. On the Location for Database, Log Files, and SYSVOL page, accept the default settings and then click Next

13. On the Directory Services Restore Mode Administrator Password page, type and confirm the password, which can be different from the domain Administrator account password.
