IIS - create well-known folder

Using file validation it is required to place a file on a specific folder location on the web server. The location needs to be an hidden directory, usually this is done by adding a dot in front of the folder name. Simply adding a dot in front of the folder name is not possible within Windows Server. There are two workarounds:

End with a dot

  1. Create a new folder within the file structure of your (web)server and name it ".well-known.", do not forget the dot at the end.
  2. The folder is now reachable via the internet.

Virtual Directory

  1. Create a folder on the C-drive, name it “well-known”. In the recent created folder create another folder named pki-validation. Example: C:\well-known\pki-validation
  2. Place the text file in the “pki-validation” folder.
  3. Open the IIS Manager on the server, right click on your site and select Add Virtual Directory....
  4. In the Alias entry fill in “.well-known” and in the Psychical Path entry fill in the path to the Well Known folder. Example: C:\well-known
  5. End with OK, the folder and files within should work properly now.
