Hi Guys

when i inhereted my network we had two subnets after a long time i've migrated everything over to one subnet, now all i have left is a reverse lookup zone for the subnet everything has been moved off, when i look at it there are enteries for my domain controllers and a pointer (PTR) for domainname.com

if i was to delete this reverse lookup zone would i need to recreate the pointer (PTR) domainname.com in the reverse lookup zone for the subnet im keeping.

hope this makes sense

Do those entries also reside in the reverse lookup zone for your current subnet?

Is domainname.com your AD domain name?  If so, you can create that PTR record if you want, but I don't believe it serves a purpose at all.  If that's the name of another domain, you may want to create it, just in case someone else put it there for a reason.  I'm not sure what that reason could be, though...
