1.7 Versioning and Capability Negotiation

  • Article

The Group Policy: Encrypting File System Extension does not provide versioning or capability negotiations.

All EFS Group Policy settings have unique definitions, and all implementations are required to support a base set of options. Thus, the only differences between implementations are in the sets of additional options supported. Due to the nature of the Group Policy configuration store used for EFS settings, a domain controller (DC) can store and maintain even those settings which its Group Policy: Encrypting File System Extension do not support.

In a heterogeneous environment, it is expected that some client computers will not recognize some settings specified here. A client will not be able to use the administrative plug-in to configure those settings that it does not support. However, the EFS administrative plug-in will neither modify nor destroy any settings it does not support.
