Why the domain cannot be found when the Win2000 auxiliary domain controller is installed

The primary domain controller and the secondary domain controller are the arguments in WINNT, and win2000 is no longer distinguished. Here we use winnt for convenience:

The first time: the secondary domain controller cannot be found when it is installed. Resolve the domain name starting with www. To the IP address of the primary domain controller. OK

Second: After the above modification, the domain controller still cannot be found, and the DNS settings are checked. The original local DNS is used for Internet access convenience, and the preferred DNS is China Telecom, the secondary parameter is the IP address of the master domain controller.

Note: The DNS and the primary domain controller are installed on the same machine.
