  • metadata cleanup have done properly. How was it done? – Greg Askew Aug 28 '18 at 10:28
  • we demoted it gracefully, then on other dc we searched in ad/dns and all other ad related tools for old dc ip/name and removed it. – iBBi Aug 29 '18 at 5:09
  • this error appears in event log daily in morning. however repadmin and other things showing all things ok . – iBBi Aug 29 '18 at 5:10
  • I forgot to update this post. The problem was sorted. Reducing the TOMBSTONE life period from 700 days to 1 day, and later all warnings errors sorted. (700 days was set few years back for some auditing test purposes) – iBBi Sep 28 '18 at 10:43
