Correct revocation configuration problems
When the Online Responder service encounters an error while attempting to load its configuration, this can indicate that the revocation configuration has been corrupted. To correct this:
Follow the procedure in the "Create a valid revocation configuration" section.
If this does not resolve the problem, follow the procedure in the "Delete a revocation configuration from the registry" section, and then follow the procedure in the "Create a valid revocation configuration" section again. If the corrupted revocation configuration occurs on the member of an Array, delete the revocation configuration by using the procedure in the "Delete a revocation configuration from the registry" section, and then use the procedure in the "Synchronize members with an Array controller" section to re-create the revocation configuration.To perform these procedures, you must have membership in local Administrators, or you must have been delegated the appropriate authority.
