I run two nameservers on NT 4.0 using the built-in Microsoft DNS to support
my web hosting of multiple sites, and mail server. I never bothered to have
my ISP delegate reverse DNS to my nameservers, however over the past few
days AOL has blocked my servers because there was not rdns entry. I asked my
ISP to delegate the RDNS, but it doesn't seem to work. Am I doing something
wrong? I thought NT DNS automatically set up all the reverse dns entries if
you ticked the box.

Hi,

You will need to create the reverse lookup zone(s) in your DNS server. The
you can create PTR records for your hosts. (when you create new HOSTS
records you check the box to automatically create the corresponding PTR
records.

Thanks! That worked great! Is there an easy way to populate the zone without
deleting and recreating records or manual editing?
