    time appears this warning in the event viewer (Directory Service Log):

    Hi
    Start by checking 2 things:
    -Antivirus is looking at your NTDS Folder.
    -Disk performance is bad or disk is starting to crash or having other
    performance problems.

    hi Jorge,
    i had installad another DC and replicated AD information on this server
    all roles and AD objects. Then the first server was sutting down and off.

    Now AD is ok.

    I think it was a hw problem (like say you).

    thanks

    Justin,
    assuming this is recurring error, other than the checking th eobvious
    (hardware problem), you might want to verify firmware/drivers for your disk
    controller and monitor disk performance to determine if these do not come
    into play...
