The Resultant Set of Policy Provider (RSoPProv) service enables you to connect to a domain controller, access the WMI database for that computer, and simulate the application of a given set of Group Policy settings which is known as the Resultant Set of Policy (RSoP). This simulation is commonly referred to as the RSoP Planning mode.

If this service stops on a domain controller, the RSoP Planning mode simulation is unavailable on that domain controller. RSoP must run only on domain controllers; member servers and workstations do not need to run this service to be included in the planning mode simulation.

This service is installed by default in Windows Server 2008 R2 and its startup type is Manual.

When the Resultant Set of Policy Provider service is started in its default configuration, it logs on by using the Local System account.

The Resultant Set of Policy Provider service is dependent upon the following system components:

• Remote Procedure Call (RPC)
• DCOM Server Process Launcher
• RPC Endpoint Mapper
