Hello, I am a sysadmin for a school district in alaska. We have roughly 1000 mac clients running 10.6.8. We are using the golden triangle with our clients bound to active directory and open directory. DNS is running internally on our 2008 R2 DC. Can anyone offer suggestions as to why I have a select few clients that appear to be registering reverse DNS(PTR) records? I was under the impression that EVERY domain bound machine should generate a reverse dns record.
