Windows 7+ Not registering Reverse DNS

Not sure if anyone else besides me uses a network device for DHCP anymore but if you do this is for you.  I've never been a fan of how Microsoft apparently wants you to setup DHCP, on a friggin Windows Server.  Why on earth would you do this when your firewall, router, IPS, or basically anything else besides another Windows Server does the job just as well?  According to Microsoft this is blasphemy and as such starting with Windows 7 they punish you.

No longer will a Windows client register its PTR record automatically without any extra GPO settings.  Windows XP did it just fine but ce la vie Windows 7 and beyond does not do this.  To fix this you either have to configure the Windows client to do it individually OR the lazy way is to configure a GPO for this.


Computer Configuration/Admin Templates/Network/DNS Client; Configure "Primary DNS Suffix" with your domain's DNS suffix and then Enable "Register DNS records with connection-specific DNS suffix".  Once you do that and allow the GPO to take effect you'll be rewarded with properly registered PTR records.
