I have Windows Home Server running on a computer I put together, but I have zero experience with trying to get any cameras running with it. There is an IIS Manager in WHS, although I don't know if or how much it is crippled compared to typical Windows Server editions.
If you haven't already, check out this plugin for WHS called Whiist.

"Whiist is a Windows Home Server Add-In that allows you to create and manage web content on your Windows Home Server." I haven't used it much, but it might be very helpful if you create additional sites/pages.
