If your page is just html, then you could run it from any PC. When the page opens in Internet Explorer, it will display. However, some web pages require processing BEFORE they display. For example, an ".asp" page requires this. You need a special program to do that preparation before display. IIS performs this task on small PCs. It is usually stored on your windows installation disk, but you have to do a custom installation to install it...it is not included in a "typical" installation of Windows.
I don't know what "PWS" is, so I can't comment on that. Perhaps it is an older program that performs the same task.
