The paper studies the Dirichlet problem for the Stokes resolvent system for bounded boundary data on bounded and unbounded domains with compact Ljapunov boundary. (The boundary might be disconnected.) For a bounded domain we prove the existence of a unique solution of the problem such that the velocity part is bounded. For an unbounded domain we prove the existence of a such solution. But this solution is not unique. We characterize all solutions of the problem. As a consequence we study bounded solutions of the Dirichlet problem for the Darcy-Forchheimer-Brinkman system At last we prove a generalized maximum principle for a solution of the Stokes resolvent system such that the velocity part is bounded.
