Routine Description:

    This service is called if a binding breaks when a context_handle is
    still active.

    Note that the RPC runtime will eliminate any race condition caused
    by an outstanding call to the server with this context handle that
    might cause the handle to become invalid before the rundown routine
    is called.

Arguments:

    SamHandle - The context handle value whose context must be rundown.
        Note that as far as RPC is concerned, this handle is no longer
        valid at the time the rundown call is made.

Return Value:


    None.
