Microsoft DNS has entries of domains that are not ours that's generated by Active Directory

lawemcsd used Ask the Experts™

I am noticing a lot of domain entries in our Forward Lookup zones.  The domains are mainly of Advertising providers like,,'s over 100 entries.  I'm trying to figure out what's generating these domains in my DNS server.

When I try to delete one of the entries it says "This is an Active Directory-integrated zone...."

I can't seem to figure what in Active directory is generating these entries.
