To begin connect to your web server as an administrator and do the following:
- Create the a well-known folder in a easily accessible location, such as within your Documents folder, or directly on the c:\.
- Drill down on well-known and create a folder inside of it named pki-validation.
- Drill down on pki-validation and move/paste the Hash File that was downloaded from your certificate-order’s validation page.
- Open IIS Manager and right click on the website, select “Add Virtual Directory…“
- For the Alias Entry field, enter .well-known and for the Physical Path field enter the location of the new well-known folder from Step 1.
- Press OK to save the input and make the file accessible on the website.
Some common problems after creating the directory include receiving a 401 error on the hash file page. You can correct this by:
- Open IIS and select the website that received the 401
- In the middle pane, look for the IIS section and open the Authentication icon
- The middle area changes; select Windows Authentication and then click Providers from the Action pane on the right
- The common issue is that NTLM is not at the top of the list. Move it there to correct the error.
