Getting errors with even ID's of 507. 508. 509, and 510\nAll errors happening around the same time every day, between around 8am and 9am\nUsers reporting login errors, severe slowdowns access network resources (printers, email, shares) during this time\nErrors are for taking an abnormally long time to read or write from files in C:\Winnt\NTDS directory (ntds.dit and edb.log). Read/writes succeed but take up to 100 seconds to process. Error mentions possible hardware failure\nThese errors seem to have started after taking an old NT4.0 BDC offline\n\nAny ideas on how to clear this up would be greatly appreciated.
