I have WIndows XP Pro on my computer and when I did the original install I did not choose to install Int. Information Services. Now that I need it I went back and tried to add it via Add/Remove Windows Components and it is prompting me to insert the XP Service Pack 1 CD. I have the original XP CD, but not a SP 1 CD. I have run WIndows Update routinely and have all the fixes/patches applied. I go to the MS Web Site to find the SP, but it sends me to the Windows UPdate site and since I already have everything installed there is nothing new to add. Can anyone tell me how to get IIS 5.1 (or PWS if it is still called that) installed? Thanks!
