PWS is not a good product, it's buggy and difficult to install. I've had lots of trouble just getting it up and running.

As the name states, it's a personal web server, I think only 10 users can access it at the same time. What happens if you exceed that number, I don't know. Anyway, it's probably gonna give you a lot of headache using it.

That said, PWS can be used for one thing: Launching active server pages(ASP) in the development phase. If you are a web-programmer it might come in handy, but internet information server(IIS) shipped with win2000 and XPpro is the better choice.

But if you just want a regulart server showing static web pages or you want to look into personal home page tools(PHP, an excellent alternative to ASP), you should use Apache.
