I was thinking about upgrading to win2k professional but it is important that i have some type of web server software to do development work. I know win2k server comes with IIS 5, but professional does not. What type of server software should professional use. Will IIS 5 work with it? If so, where to i find IIS 5. Many people have told me it was on the Win2k Resource Kit, but my friend said he couldn't find it in any of the directories. If IIS 5 doesn't work, or is not available, will IIS 4? What about PWS? I really wanted to know this before I upgraded. Thanks for any help.
