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?

Answer 1

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

Answer 2

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

OR

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
