  • ntds.dit online defrag terminated

    Hey guys, I hope someone can help me with this. I have looked through some google search results for a solution to this issue and havent got very far. So im hoping someone here can help me. For the past month one of my customers SBS 2003 premium machines has been producing the following even log entries.

    Category: Online Defragmentation
    Event ID: 705


    NTDS (1612) NTDSA: Online defragmentation of database 'C:\WINDOWS\NTDS\ntds.dit' terminated prematurely after encountering unexpected error -1018. The next time online defragmentation is started on this database, it will resume from the point of interruption.


    Also get

    Category: Database Page Cache
    Event ID:475

    NTDS (1612) NTDSA: The database page read from the file "C:\WINDOWS\NTDS\ntds.dit" at offset 4194304 (0x0000000000400000) for 8192 (0x00002000) bytes failed verification due to a page number mismatch. The expected page number was 511 (0x000001ff) and the actual page number was 2309737967 (0x89abcdef). The read operation will fail with error -1018 (0xfffffc06). If this condition persists then please restore the database from a previous backup. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.

    I know the last message states that the problem is likely hardware related but I have run diagnostics on memory and the hard disks and I havent found any issues. Is there something else I can check before I start replacing hardware? Any help would be greatly appreciated.

    A -1018 error on a ESE database is usually a very bad thing. Take a look at this article:

      Has your Active Directory changed in any major way in the last month since you started getting these messages? Have you a System State backup from before this error occurred? If yes can you build (even in a virtual machine) a base copy of the Windows part of your SBS installation and then try a System State restore?
      If that is successful, backup your current installation ENTIRELY and try a System Restore on your production machine. Remember it will roll back any AD changes you made in the last month including user passwords.
      I don't know your level of expertise and I certainly don't wish to insult you, but if none of the above makes any sense to you, engage an IT professional/specialist or call MS PSS.
      TIA

        Don't worry about it how are you to know my level of knowledge. The big problem here is that this isnt normally my customer and it belonged to a guy that just quit. I took over the customer and find these errors and also find that their backup hasnt been working for the past 3 months. So that is a little unnerving that I dont have a good back that is from within the last 3 months. I knew that this was probably going to mean a rebuild but I have been hoping that I was wrong lol.

          Now you know why he quit!
          Ughh - this is a horrible situation because you are made to look like the bad guy, whatever you do. However, I would rebuild because if youdon't have a good backup for 3 months and the AD database is giving you problems, who knows when it is going to turn around and bite you.
          You probably can't even Swing safely as your AD could be corrupt.
