I got this message today after setting up a very basic VPN with Server 2008 (yes, an article for that is coming).
After logging on successfully to the VPN, I noticed I couldn’t ping my server by name. I chalked this up to a badly (or rather, mis-) configured DNS server. I could ping the IP, though, so I plugged that into the remote desktop client.
Lo and behold, the above error message appeared.

AD DS: DNS Server requires static IPv4 and IPv6 IP Addresses
Posted by Harv in DNS, Quick Tips, Server 2008, Troubleshooting, Windows on December 30, 2009
While installing and configuring Server 2008 (Standard), I decided to set up the AD DS service.
AD DS requires that the DNS service be set up as well. DNS doesn’t function properly if you’re getting a DHCP address.
I personally haven’t yet made time to to educate myself about IPv6, though I should. The DNS setup process will complain if you do not have a static IPv6 address configured.
My server has two NICs. Their IPv4 addresses are 192.168.3.2 and 192.168.3.3, respectively.
I went to the following website – http://www.subnetonline.com/pages/subnet-calculators/ipv4-to-ipv6-converter.php, plugged in the respective IPv4 addresses, and used the tool to pull out the equivalent IPv6 address, subnet mask, and default gateway.
I then also set the primary DNS server to 127.0.0.1 (in IPv6 notation of course, which I believe is 0:0:0:0:0:0:7f00:1),
and my local router – 192.168.3.1, again in IPv6 notation.
