to run ntdsutil and still can't be recovered. Can anyone help me to resolve this problem? I'd read some web info and nearly all of them are having below error message:- lsass.exe-System Error: Security Accounts
Ntds Isam 467
Manager initialization failed because of the following error: Directory Service cannot start. Error Status: 0xc00002e1. Please click OK to shutdown this system and reboot into Directory Services Restore Mode, check the event log for more detailed information. However, for me, the error code is 0xc00000e5 instead of 0xc00002e1. Is there any difference?

At the same time, you will need to perform the steps below before re-promoting the server: 1. Seize FSMO roles to the existing DC in the domain. For the detailed steps, you can refer to the following Microsoft Knowledge Base article: Using Ntdsutil.exe to transfer or seize FSMO roles to a domain controller http://support.microsoft.com/?id=255504 2. Remove remnant entries of the corrupted DC from AD database. How to remove data in Active Directory after an unsuccessful domain controller demotion http://support.microsoft.com/?id=216498 3. Then, you can re-promote the server *Solution 3: If this is the only DC, you can use ntdsutil.exe to repair AD database ntds.dit. However it might not completely resolve the issue. In some situation, certain configurations will be lost.

Its a SBS 2011 premium server I can start in directory recover mode I can't start in safe mode or normal mode https://www.experts-exchange.com/questions/28045541/Repair-NTDS-DIT-that-have-bad-checksum.html :-( First time i tried to run ntdsutil and the file command it failed, i couldnt run it. I had to run the go fix command and after that i can run the file command. But i cant fix the bad checksum so i cant start it in normal mode. Is there any way to repair the ntds.dit file in any way, some program or other way to do it? Is it possible to see what the checksum should be and correct it manualy? If its not possible to fix the ntds.dit file, is it possible to start AD on scratch and connect it to the exchange server? 0 Question by:per-w Facebook Twitter LinkedIn Google LVL 5 Best Solution byvin_shooter I think then its not possible to revert the situation.

may have a replication issue so I started looking into it and to give a brief background of the environment.. we have almost 48 Windows 2008 R2 domain controllers globally, so we http://asknicks.blogspot.com/2013/05/active-directory-database-corruption.html needed to find out where and how the replication is broken.. Now, i needed a tool that can go and check all domain controllers to summarize the replication inbound and outbound replication status.. so Ipulled up "REPADMIN"to find out the inbound and outbound replication status of my domain.. I ran "repadmin /replsummary" and i started counting dots on the command screen which represent the progress. So after few minutes active directory of processing, I had a summary report of the servers and unfortunately i found one of our DCs hasn't replicated in last 16 hrs (quite worrying, huh!! ). But just next to it had a reason of the failure which said "The replication operation encountered a database error" Oopps, this is getting interesting now.. So, i logged in to the Domain Controller reporting database issue to investigate further and ntds checksum error fix it. The directory service Event log showed me Database index corruption errors.. hmm interesting..

This willdefinitelyskip a heartbeat of most of the AD administrators.. :( so we ran little PowerShell script to quickly check all domain controllers for Event ID 467 and make sure we are not spreading the corruption over to other servers. Thankfully no other DC isexperiencingthe corruption.. Generally, the corruption can be caused by numerous reasons but i had few in my mind that requires a check there and then... Hardware Outdated Drivers/firmware especially disk controller & controller cache. Sudden power loss Lingering objects Time to fix it then.. most of the time the Domain Administrators prefer to go ahead and rebuild the domain controller and sync everything back, but the real concern is how many changes does this box hold and what would be the impact if we go ahead with demote andre promoteof the server.. hmm, so in our case we deci
