on one of my windows 2012 server
I am getting below error
NTDS (648) NTDSA: A bad page link (error -327) has been detected in a B-Tree (ObjectId: 174, PgnoRoot: 655) of database D:\windows\NTDS\ntds.dit (407594 => 22348, 359484).
I had got answer from bas 2754 ,
Follow the directions on that page and it is your best bet to try to recover if you do not have a backup. If you have more than one domain controller you may be able to remove this controller from the domain and add it back. If it is the only controller then a restore or rebuild are your only options.
which solution I accepted, but I have to reopen because I have one question:
do I need to do before demoting and repromoting server.
1) Remove antivirus from the server
2) Perform an offline defrag of ntds.dit if not done already
we have couple of other DNS servers , should we do during office time
HOW LONG CAN I CONTINUE WITH THIS ERROR
is it required
