Description
To ensure that 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 DoD 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.
