First, I have no idea how this was working to begin with, but now this is broken.
All I did was replace an on-prem email spam filter, with a cloud based server.
My vm xfer to other branches no longer works. I was told to 'simply' create DNS entries for the controllers on my internal DNS. I can not do this as the "PTR record cannot be created, probably because the reference reverse lookup zone cannot be found"
Should I manually create the reverse lookup zone on my DNS?
