I used PWS for my first web server but I think it sucks.It a bi#tch to get perl ,and PHP to run.If you like ASP and stuff then go fo it.But your better of with IIS or apache for windows.
But I like abyss web server because Its easy to configure and i does not take alot of resources from your computer.
just a question ..you know that you can only have 10 connections at once with all windows boxes that are not servers(win 2k pro,98,NT workstation,Me)?
