I was trying to do a reverse dns lookup for one of our Windows 7 machines and it fails.  The nslookup with the host name works without a problem.  I looked at DNs and see that their is no entry in the reverse lookup zone for our windows 7 clients.  Why is this?  The DNS A record has the option to update the asocaited ptr record selected.  I tried removing it form DNS and running an ipconfig /regiosterdns form the Windows 7 workstation with the same results.  Is there a way to resolve this so reverse dns lookups work?

Do you use domain and users are domain users and workstation are registered in domain? If not, it maybe isue that is allowed only secure dynamic updates - try change properties for subnet in zone.

I check windows7 workstation -  I enabled "use this connection's DNS suffix in DNS registration" in windows7 and vista adapters TCP/IP advanced settings - maybe it is the solution for updating DNS.

I installed newest service packs and latest updates to my windows 2003 std and SBS 2003 Premium servers, Vista and Windows 7 workstations and have no problems with servers and workstations (winxp pro and home, vista buss and windows 7 - Office 2003, Office 2007, Exchange 2003).

Also I set my DHCP server (DNS tab):
"Always dynamically update DNS A and PTR records" and "Dynamically update DNS A and PTR records for DHCP clients that do not request updates".

I have the following set in my DNS tab on by DHCP server:

Enable DNS Dynamic Updates according to the settings below:
Always dynamicaly update DNA A and PTR Records

-Discard A and PTR Records when lease is deleted

-Dynamicaly update DNA A and PTR Recordsfor DHCP clientsthat do not request updates (for examplr clients running NT 4.0).

Still with no luck.

Applying the policy under DNS in computer configuration for "register dns records with coonection specific dns suffix" for the default domain GPO resolved the issue.
