i have 2 DC's , DCa and DCb, dca has all 5 fsmo roles and dcb is used basically as a backup dc and fileserver. both are syncing ok regards to users etc , but i cant open gpo on dcb all of a sudden!
when i try it states the specified domian controller could not be contacted!
what could be my issue?
last week dc_a was down for approx 6 hrs, but normal service seemed to commence once brought back up
