I get a Certificate Error when visiting this and other DoD websites.

If you are experiencing issues with your web browser indicating our website should not be trusted or is using invalid certificates, the solution is to install the DoD Root Certificates.

There are two methods to accomplish this:

  1. For Microsoft Windows users use the instructions at this link: Method 1.
  2. For Microsoft Windows and Mac OS X users follow the instructions at this link: Method 2.

When I visit the USAMRAA website I get a Certificate Error: Navigation blocked message.

What is the purpose of the DoD Root Certificate?
A certificate is a digital document providing the identity of a website or individual. DoD websites and DCMA uses a certificate to identify itself to its users and to enable a secure connection.

Certificate Error: Navigation Blocked
If you receive "Certificate Error: Navigation Blocked" in IE-7/8 while visiting any USAMRAA secure sites (https), more than likely you do not have the DoD Root CA 2 certificate installed in your IE-7/8 browser. Installing the DoD Root Certificates will allow your web browser to trust the identity of websites whose secure communications are authenticated by Department of Defense agencies. The DoD Root CA 2 certificate is included with InstallRoot_v3_13.exe.


Installing the certificates

  • Click on the InstallRoot_v3_13.exe link and select RUN. InstallRoot_v3_13.zip .
  • The install will scroll in your MS DOS window while in progress.
  • When you see the message, "Type the return key to terminate", the install is complete.
  • Hit Return to close the DOS window.
  • If you are running InstallRoot_v3_13.exe on MS Vista or MS Windows 7, you may encounter an additional popup box, Program Compatibility Assistant.
    • The Program Compatibility Assistant box will prompt you to select one of the following choices:
      • Reinstall using recommended settings.
      • This Program Installed Correctly.
    • Select "This Program Installed Correctly" to complete the install.

Checking the installed root certificates

  • Open IE 7/8.
  • Click Tools/Internet Options/Content/Certificates.
  • You should see a list of root certificates including DoD Root CA 2 under the Trusted Root Certification Authorities tab.
  • Once verified, close the internet options windows by selecting close and cancel.
  • Your browser is now configured to visit USAMRAA secure sites.
