IIS + Linux servers load balance

[hiusing]

I have couple of Windows and Linux dedicated server from different provider would like to cluster them for load balance. The main dns server is in a Windows box and I want to use a simple round robin DNS for load balance solution. As you know round robin DNS does not protect against crash server so I'm about to write a simple program to ping each other from the DNS server, and update (add/remove) the DNS with according to the status of the ping in the web fram.

Do you know a method or api to modify DNS in windows server?

Thanks,
Naki

Even if you do change the DNS as soon as the server crashes, it will still take some time for the DNS changes to propogate across the Internet.

I don't think round robin DNS will do what you want it to do.
