So, I did something quite foolish (it's a long story) and accidentally started an uninstall of DNS on one of my domain controllers. Fortunately, my Active Directory appears to be functioning properly, and the uninstall seems to be pending completion until reboot.
The DNS Manager console is still active on the DC in question. I only have one conditional forwarder configured and a few forward lookup zones that are external to my AD domain. These all still appear in the console, and all resolve properly when queried.
%SYSTEMROOT%\system32\dns on the DC in question does not contain any .dns files specific to my domain and the 'mydomain'.dns file on my other DC does not contain any of these external forward lookup zones-- also, the other DC's DNS Management console also contains all of my zones.
So it seems that all of this info is stored in Active Directory (all as integrated zones) instead of .dns files, and therefore things are not so bad. Is this correct?
Also, is there anything I might need to look out for when rebooting the server and reinstalling DNS (other that possibly having to reconfigure my conditional forwarder)?
