To add a Windows 2000 computer as a domain controller in an existing Windows NT 4 domain, John Doe can follow these steps:
B. Install Windows NT 4.0 server on the new computer and designate it as a BDC in the existing domain, then promote it to a PDC and then upgrade the computer to Windows 2000 server.
Explanation:
- Windows NT 4.0 and Windows 2000 use different directory services. Windows NT 4.0 uses the NT Domain structure, while Windows 2000 uses Active Directory.
- To add a Windows 2000 computer as a domain controller in an existing Windows NT 4 domain, you need to first upgrade the existing domain to Windows 2000 Active Directory.
- The process involves adding a Windows NT 4.0 BDC, promoting it to a PDC, and then upgrading it to Windows 2000 server.
- By designating the new computer as a BDC in the existing domain, John can ensure that it replicates the existing domain information.
- After promoting the new computer to a PDC, John can then upgrade it to Windows 2000 server, which will allow it to function as a domain controller in the existing domain.
Option A is incorrect because shutting down the PDC on the existing Windows NT 4.0 domain and installing Windows 2000 server on the new computer will not automatically integrate it into the existing domain.
Option C is incorrect because shutting down the PDC on the existing Windows NT 4.0 domain and running the Active Directory installation wizard on the new computer will not automatically integrate it into the existing domain.
Option D is incorrect because installing Windows NT 4.0 server on the new computer and designating it as a PDC in a new domain with the same NetBIOS name as an existing domain will not integrate it into the existing domain. Upgrading the computer to Windows 2000 server is also not mentioned in this option.
