Aloha,
   I have a super strange issues with Windows 2008 AD.  Our DNS Server (AD enabled) is having a lot of issues with the reverse lookup zone.  I can do forward lookups (EX.  xyz.somewhare.com)
but I can not do reverse lookups (EX. xyz).  I am not sure how to fix this situation.  We do have a pure Windows 2008 AD.  The servers are no in Native Mode, they are in Mix Mode.  The servers were migrated from 2000AD to 2008AD.  

Any help would be great :)

Thanks,
supertechhawaii

I'm not sure what you mean by reverse lookup.  My understanding of a reverse lookup is you provide an IP address and have the DNS server resolve the DNS host names (ie: 192.168.1.4 resolves to xyz.somewhere.com).

Is this what you are having trouble with?

Aloha mlongoh,
   That is the exact issue.  This is for all my reverse lookup zones.

Thanks,

How many different subnets do you have and how many appear to be represented in DNS?  Are you manually populating any entries or relying solely on dynamic updates to populate DNS?

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I only have 1 subnet.  I am relying on dynamic updates as well as static entries for the DNS.

I have checked and the zone is an AD zone.

Hi,

Reverse lookup zones support the resolution of IP addresses to host names. Although they are optional in most networks, reverse lookup zones might be necessary for certain secure applications that require the validation of IP addresses.


Try recreate your reverse lookup zone

This article is for server 2003 but more or less it's applicable.
