Create an IIS Virtual Server
You must have one IIS (Internet Information Services) virtual server for each Instant Messaging Home Server you create. In most situations, you need only one Instant Messaging Home Server, and you can use the virtual server provided by the IIS snap-in, Default Web Site. When you need to install more than one Instant Messaging Home Server on a single machine, you must create an additional IIS virtual server for each additional Instant Messaging Home Server.
