Internet Information Services

Internet Information Services (IIS) iS Microsoft’s Web server suite, which includes aWeb server, FTP server, NNTP server, and a few other things. Originally called Internet Information Server, Microsoft partly changed the name in version 5.0; “Server” became “Services” to reflect a shift in Microsoft’s view of what IIS really is. Earlier, IIS was more or less an add-on product to Windows NT; now it is an application running like a service closely integrated with the operating system.
