  1. First make sure the file 'NSAccess.aspx ' exist in :\Program Files\Altiris\PluggableProtocols\Web\NSAccess.
  2. Then in IIS check 'Altiris\PluggableProtocols\NSAccess'  and make sure it can be opened and has the correct path.
    • Right click on NSAccess (Or the page you see in the error) > Manage Application > Advanced Settings
    • The physical path should be  <Installed Drive>\Program Files\Altiris\PluggableProtocols\Web\NSAccess\

Save and restart the IIS.
