How to Check IIS Versionby Lysis ; Updated September 28, 2017
Internet Information Services (IIS) is a hosting service provided by Microsoft with the company's server operating systems. It hosts website applications, provides FTP tools and runs ASP.NET framework code. An older IIS version will not run newer ASP.NET applications, so it is important to check the IIS version before developing. The IIS version information is provided in the management console, so it only takes a few steps to find the version on your Windows 2003 server.
Click the Windows "Start" button and select "Control Panel."
Double-click "Administrative Tasks."
Double-click "Internet Information Services." This opens the management console.
Click the "Help" menu at the top of the window.
Select "About Internet Information Services." This opens a window that shows the IIS version you are running.
For Windows XP operating systems, the "Control Panel" icon is found directly after pressing the Windows "Start" button.
