Windows – How to refresh a Host record? Win 2008 Server DNS

Sorry, I forgot to put in the question that these are static IP's. I realize I could add the DNS entries on the Windows side manually as well, but I'm not actually in charge of that Windows DNS server.

If you don’t have control of the DNS server, and if the DNS isn’t set up to allow non-secure updates, and it isn't set up to update based on DHCP assignments, and you have a static address, then you are probably out of luck.

Since this system has a static address, is there some reason you can’t just contact the person who runs the DNS server and ask them to add a record for your system?

I don't know the windows way to do this, but the BIND way to do it is:

[root@dhdx421 internal]# head -n 20 example.com
$ORIGIN .
$TTL 21600      ; 6 hours
example.com              IN SOA  ns3.example.com. hostmaster.example.com. (
                                2009111201 ; serial
                                10800      ; refresh (3 hours)
                                3601       ; retry (1 hour 1 second)
                                259200     ; expire (3 days)
                                21600      ; minimum (6 hours)
                                )
                        NS      ns2.example.com.
                        NS      ns3.example.com.
                        A       172.18.1.100
$ORIGIN example.com.

The A record above is the example.com record. Specifying *.example.com means "anything".example.com, but "anything" can't be null as you've specified a "." and periods have special meaning in DNS.

Additionally, keep in mind that if you're overriding someone else's DNS, unless you setup forwarding properly, you will only be able to resolve the addresses that you've overridden (i.e., made your server authoritative for).
