How can I find out which version of Microsoft Internet Information Services (IIS) my server is running?

Question

My server is running with Windows Server 2003 SP2. How can I check for which version of IIS it is running?

Solution

You run a simple asp script on your IIS server:

response.write(Request.ServerVariables("SERVER_SOFTWARE"))

Or look for ASP.DLL (under system32, I believe) right click it, choose properties and check the file version.

However on Windows Server 2003, you are almost certainly running IIS 6.0

This DLL is most likely in C:\Windows\system32\inetsrv\

There is no asp.dll in C:\Windows\System32\inetsrv (server 2012 here).

Look like from IIS 7.0 onward there is no ASP.DLL.
