very basic row laytout won't work on server

[Jorgensen]

I have 
- created an exact copy of this example (see below) https://www.w3schools.com/w3css/tryit.asp?filename=tryw3css_ref_row
- copied the code to a test.html file
- copied the file to our company server 
- copied the to an extern www server
 

Internet explorer displays the exact same file different on intranet vs www. When seen on the intranet internet explorer seems to ignore the setting "w3-row",  while it works fine on the www server. 

Chrome shows the file fine on both intranet and on www. 

can anyone help solving this issue, as it drives me..............

thanks

Can you open both examples with Chrome and show us the F12 screen (it sometimes displays errors).

Does this file get opend? "<link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css">"
