The NPS video portal system, when playing an encrypted video stream, uses SSL certificates issued by the Department of Defense.  Your browser must trust these DOD-issued certificates or else you may get an error or simply not see the player at all.    Not trusting the DOD certificates may cause issues with other websites or services as well.   Download the public certificates needed using one of the methods listed below.  

The Firefox browser on both Mac and Windows maintains its own list of trusted certificates, and does not get these from the operating system.   Firefox users must use the GUI-based tool (see below), or manually install the certificates one by one.

OPTION 1 - Install All DOD Root Certificates (Windows Only)

The InstallRoot application is the most simple and straightforward way to install all DOD certificates in your windows operating system.   The links below will let you download the tool from the DISA.MIL website.

  • Download the InstallRoot Application for Windows (recommended - requires Java installed)
    The GUI-based tool is the best way to install the root certificates for both MSIE/Chrome as well as Firefox in Windows.  It requires Java to be installed on the workstation.  Don't forget to run it twice - once for the Windows certs, and again for the Firefox certs.
  • Download the InstallRoot command line tool for Windows (Java not required)
    The command line tool for Windows installs the root certificates for Internet Explorer and Chrome ONLY. Firefox users must use the first link, or manually install them from the instructions below.

OPTION 2 - Manually Install the DOD Root Certificates (All Systems / Browsers)

You can manually download the root certificate and any intermediate certificates needed when using SSL-based websites or services at NPS.   

The CA-2 root is always required, and you'll also need to install the intermediate certificate for each application you intend to use.  E.g. For the NPS streaming video, your browser needs to trust CA-2 and both CA-21, CA-27, and CA-28.     By installing all the certificates, your web browser will trust all DOD sites that use SSL - not just those currently in use here at NPS.
