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.
