I'm running WinXP Pro SP3 and IIS 5.1 on my home dev machine. As far as I can tell IIS 5.1 only allows me to host one website, which is a problem because I'm working on three at the moment. Is that right, and, if so, is there any way around that limitation?
EDIT: This is just for dev/test purposes - I don't want to actually host any live websites, or even let anybody apart from me access them.
This is actually possible to do without any kind of addon. XP Pro will still allow multiple sites to run under IIS, but they have removed the option to configure this from the GUI. They have also removed the ability to have more than one site run simultaneously. Using the scripts found in the \Inetpub\Adminscripts directory you can add additional sites, and then use the IIS admin snapin to toggle which one runs.
