We get a remote site with a Domain Controller 2012R2 and a number of servers.
We are going to repair the hardware for that particular Domain Controller.
For servers at that site, we have assigned DNS Server = Remote Site Domain Controller and HQ Domain Controller. However, it seems that whenever the Remote Site Domain Controller is down, servers at Remote Site are not able to access DNS properly.
Is there any easy way for us to check whether servers at Remote Site can make use of the HQ DNS Server for name resolution ?
