Cant comment on which has IIS, but i understand that the Bidness & Ultimate versions have remote desktop and the home versions do not. By the way, i noticed that the Dell config store had changed their setup from Vista only OSs, to XP or Vista.

>Well, it finally happened to me – my computer (the one with all the bells and whistles you could imagine) gave up the ghost. Three years old – obsolete motherboard, obsolete video card, obsolete memory, obsolete power supply – etc. Where have I been? Technology is an evil that some of must live with. I have had hard drives go but never a motherboard. Power on - nada!

>Can someone tell me which version of Vista has IIS? I know that Visual Studio 2005 does not require IIS for ASP.NET development, “except for some functions”. With my luck without IIS, I will be creating an ASP.NET that needs it! :)
