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

You run a simple asp script on your IIS server:


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

Thanks, the ASP.DLL file helped a lot! – wahle509 Oct 28 '09 at 18:53

How do I determine which version of IIS / ASP I'm running?

If you are running Windows Server 2003, you are running IIS 6.0 / ASP 3.0


  1. Do a search for ASP.DLL on your system
  2. right-click it and select Properties
  3. Check the version tab:

        IIS 3.0 shows 1.x 
        IIS 4.0 shows 2.x 
        IIS 5.0 shows 5.0.2195.x 
        IIS 5.1 shows 5.1.2600.x 
        IIS 6.0 shows 6.0.3790.x

Thanks for the IIS versions! – wahle509 Oct 28 '09 at 18:54
This DLL is most likely in C:\Windows\system32\inetsrv\ – TravisO Jan 25 '13 at 15:03
There is no asp.dll in C:\Windows\System32\inetsrv (server 2012 here). – Pacerier Aug 14 '15 at 5:18
