Hi,<br />
I have a website that resides on four different servers, with each server being in a different data centre throughout the country (so 4 different IP's).<br />
<br />
I have configured my dns 'a' records to point to each of these ip addresses and i have enabled dns round robin within the 'advanced' tab of windows server 2003 dns console.<br />
<br />
What i want to know is, if one of my four servers was to fall over how can i prevent the dns server from giving out the ip of failed server?<br />
<br />
Naturally i realise i could just remove the 'a' record manually but is there a way of doing this automatically?<br />
<br />
Is the server clever enough to poll the individual IP's for a positive response before it provides the IP address of the site?<br />
<br />
I hope that makes sense.<br />
<br />
Thanks

DNS Round Robin Query

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
