BloodModerator February 19, 2019 at 7:11 am #614366 Have you checked the remaining DC holds the FSMO roles? Also, have you performed a metadata cleanup to ensure references to the failed DC’s has been removed? JeremyWModerator February 21, 2019 at 12:31 pm #614424 Can you run the following on a working DC and post the results (redact any info as necessary) repadmin /syncall /AdePq Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
