I have created and configured websites for some time now, but I never really understood what IIS is.
Is it an executable? A group of executables? Some DLLs? What is its relationship with W3wp.exe?
Is this explained anywhere in MSDN?
Thanks.
[EDIT] Ok, it’s inetinfo.exe. I have found a detailed description here: http://www.west-wind.com/presentations/howaspnetworks/howaspnetworks.asp
IIS is a server process that hosts web applications in a Windows environment.
Learn about it here: http://www.iis.net/
As I mentioned in the comment above: w3wp.exe is a web process spawned by IIS for each application pool that you have configured and running.
