Windows Server Note (vi): Active directory Domain Services: Additional domain controllers

Additional domain controllers:

An additional domain controller refers to all domain controllers that are unexpected except for the first installed domain controller (primary domain controller);

1, can provide fault tolerance. That is, a DC problem, the other can still continue to work, provide services;

2, improve user login efficiency. Multi-domain control can share user audit, speed up user logon;
