2.7.1.2.3 Link Speed Determination Failure
If a failure in link speed determination occurs ([MS-GPOL] section 2.2.6), the Group Policy client assumes link speed to be above the threshold and processes policy settings that belong to all CSEs. At the next scheduled policy application, the Group Policy client initiates link speed determination again in an attempt to recover from the failure. Recovery from the failure helps prevent application of policies from those CSEs that should not be invoked when link speed is below threshold.
If the link speed cannot be determined, all policies are applied to ensure that critical functionalities are in place.
