the remote server returned an error: (401) unauthorized


I wanted to thank you for sharing the set up guide for Jet Express for NAV with MS Dynamics NAV 2013 to fix the NAV license file problem. We (IT and NAV's team) followed the guidance from page 1 to page 6. When we were on page 6, the company and Jet code unit fields were not pulling any value. These fields were empty so we had to type in the company name and Jet code unit and click Test connection. After we click test connection, we got an error saying:

the URL 'http://servername:7047/instance/WS/SystemService' is not valid. The following error was reported:
The remote server returned an error: (401) unauthorized.

What does it mean when it said the remote server returned an error (401) unauthorized? and how do we do to fix this error?
