Description
To ensure users do not experience denial of service on NIPRNet when performing certificate-based authentication to DoD websites due to the system chaining to a root other than DoD Root CA 2, the US DoD CCEB Interoperability Root CA 1 to DoD Root CA 2 cross-certificate must be installed in the Untrusted Certificate Store. This requirement only applies to NIPRNet systems.

Fix Text (F-48775r1_fix)
Install the US DoD CCEB Interoperability Root CA 1 to DoD Root CA 2 cross-certificate on NIPRNet systems only. Administrators should run the Federal Bridge Certification Authority (FBCA) Cross-Certificate Removal Tool once as an administrator and once as the current user. The FBCA Cross-Certificate Remover tool and user guide is available on IASE at http://iase.disa.mil/pki-pke/function_pages/tools.html.
