IIS Grabs all IP addresses

I hadn't realised until today that if you install multiple NIC's or add additional IP addresses to an existing NIC on a machines running IIS, that IIS will grab all those IP addresses.

This was causing me a problem with a media server that i wanted to run on my SBS 2008 machine.

The answer is to tell IIS to listen only on a specified address by issuing

netsh http add iplisten ipaddress=required_ip_address

from a command prompt and rebooting.  You can then tell your media server to only run on one of the other addresses and all should be well.
