	// The GetUniqueConfigPath method is received by the server in an RPC_REQUEST packet.
	// In response, the server returns the deepest hierarchy path (up to the specified hierarchy
	// path) that contains a unique set of IAppHostElement objects. For example:
	//
	// Assume: At hierarchy path A, a set of IAppHostElement objects exist.
	//
	// Assume: At hierarchy path B (deeper than A), the identical set of objects exists.
	//
	// Given these assumptions, GetUniqueConfigPath( B ) returns path A. In other words,
	// the method returns the shallowest path that contains the identical set of IAppHostElement
	// objects as the specified path.
	//
	// Return Values: The server MUST return zero if it successfully processes the message
	// that is received from the client. In this case, *pbstrUniquePath is not NULL. If
	// processing fails, the server MUST return a nonzero HRESULT code as defined in [MS-ERREF].
