Changing Orchestrator Default URL

Hi All,
We have installed UI Path Orchestrator on our Windows Server with Windows Auth enabled. It created a site at IIS like “__https://mydomainname/” and it works fine with the local users as well as windows auth.
We want to change the “__https://mydomainname/” to something like “__https://mydomainname/uipath”.
We have tried adding an application under the default site which has helped us in opening the orchestrator at “__https://mydomainname/uipath” but when we use windows auth it redirects back to “__https://mydomainname/” and gives 403. What could be the possible root cause?
If we have to follow some other steps instead of adding application IIS, please let us know.

We are using UI Path orchestrator Enterprise edition.
