If you have applications in your environment that can run only on a Windows NT 4.0–based domain controller and if all the Windows NT 4.0 BDCs have been upgraded to Windows Server 2003 or the existing Windows NT 4.0 BDC in your environment becomes unavailable, you might need to add an additional Windows NT 4.0 BDC to your environment. You can do this by installing a new Windows NT 4.0 BDC in the domain. Prior to installing the new Windows NT 4.0 BDC in the domain, you must first add the new computer account to the Windows Server 2003 domain.

Note

  • You will not be able to install a new Windows NT 4.0–based BDC in your environment if you have SMB packet signing and secure channel signing enabled. If these security policies are enabled in your environment, modify them before installing a new Windows NT 4.0–based BDC. For information about modifying security policies, see "Modify Security Policies" earlier in this chapter.

To add a Windows NT 4.0 BDC to a Windows Server 2003 domain

  1. In Active Directory Users and Computers, right-click the Domain Controllers folder.

  2. Point to New, and then click Computer.

  3. Type the computer name of the BDC.

  4. Ensure that the checkboxes are selected for Assign this computer account as a pre-Windows 2000 Computer and Assign this computer account as a backup domain controller.

  5. Install the BDC in to the domain.
