check logs file replication between dc's too.
if have strange filelock on gpo's maybe have more problems inability modify gpo's.

maybe need restart services ad , others on these servers filelocks released if case. there third-party utilities check. check dc pdc, server in use when edit gpo's unless set setting above mr x writes.
