    SAFEBOOT registry subkeys missing, can't boot into safe mode

    Hi:

    Windows 2003 Server, can't boot into safe mode. Upon further
    inspection, subkeys for SAFEBOOT are missing from HKEY_LOCAL_MACHINE
    \SYSTEM\CurrentControlSet\Control\SafeBoot registry. That is, not
    even Minimal nor Network keys are present. ContolSet002, ...,
    ControlSet004 are either missing SafeBoot key entirely or the subkeys
    as above.

    1. What is the procedure to restore these keys, short of a reinstall
    of the opsys?

    2. Any idea how this could have happened? If a virus/trojan, I didn't
    seen anything suspicious under run/runonce (cursory inspection).

    Thank you in advance for your help.

    Used ERD Commander 2005 for boot.

    This does sounds like malware got your machine. Take a look at the link
    below to see if it helps. Another option is to boot up from the Windows 2003
    CD and run an upgrade. This will keep all current settings and roles. If the
    CD is integrated with the same SP level, then just re-run Windows Update. If
    not, run the current SP, then run Windows Update.

    Ace:

    Yes, indeed it was from an earlier infection. a Win32/Bagle worm
    variant
    Restore from older backup is not overwriting registry

    I'll do a repair from the install CD, but at some point it's about
    time to do a fresh install. Thanks.

    Ace:

    Further, I did have the Didier Stevens link open in IE when I posted
    the note. Just haven't done it, since it wasn't definitive.

    This would be the better option to running an ugrade. Let's hope for the
    best. If this doesn't work, then let's go for running the upgrade. Of
    course, the ultimate option is a clean reinstall.
