Error Status: 0xc0000001. Please shutdown this system and reboot into Directory Services Restore Mode, check the event log for more detailed information.


If this happens in Domain controller server, which is in Windows Server 2008/2008 R2 or Windows Server 2012/2012R2

Restart the server and press F8 key, select Directory Services restore mode.
Log in with the local administrator username and password
Type: cd \windows\system32

If you encounter an error stating that the Jet engine could not be initialized exit out of ntdsutil.

Type: cd\
Type: md backupad
Type: cd \windows\ntds
Type: copy ntds.dit c:\backupad
Type: cd \windows\system32
Type: esentutl /g c:\windows\ntds\ntds.dit
This will perform an integrity check, (the results indicate that the jet database is corrupt)

Type: esentutl /p c:\windows\ntds\ntds.dit
Agree with the prompt

Type: cd \windows\ntds
Type: move *.log c:\backupad (or just delete the log files)
This should complete the repair. To verify that the repair has worked successfully:

Type: cd \windows\system32
Type: ntdsutil
Type: activate instance ntds
Type: files (you should no longer get an error when you do this)
Type: info (file info should now appear correctly)
One final step, now sure if it’s required:

[FIX] NTLDR is compressed

If you have compressed the hard disk drive using the Compress drive to save disk space option under the Properties menu for your hard disk drive and have performed a non-destructive recovery or a system recovery, the following error message may appear:

To solve this issue by following steps:

1. Insert the CD into your drive. Make sure your BIOS is set to try to boot to a CD first if you know how. Most systems already do this.
2. Reboot your PC.
3. When the message "Press any key to boot to CD..." appears, do so before this prompt disappears or else it will boot normally. Wait for all of the drivers to load.
4. The 'Welcome to Setup.' screen will appear. Choose the option that says "To repair a Windows XP Installation using Recovery Console, press R." by pressing the 'R' key.
5. A list of Windows XP installations on your computer appears. Typically, XP is installed in C:\WINDOWS or C:\WINNT. In most cases it will be the first or only option in the list. To select this, press the '1' key and then press 'Enter'. Pressing 'Enter' without typing a number will cause the program to quit.
6. Where it says 'Type the Administrator password:', enter the password. If you have never set one, just press 'Enter'. The 'C:\WINDOWS>' prompt should now be showing. Type the following commands into the prompt one at a time and press 'Enter' after you type each one:

Issue: Fix a corrupt Boot.ini

As the Windows XP operating system begins to load, the Ntldrprogram refers to the Boot.ini file to determine where the operating systemfiles reside and which options to enable as the operating system continues toload. So if there's a problem rooted in the Boot.ini file, it can render WindowsXP incapable of booting correctly.

If you suspect that Windows XP won't boot because Boot.inihas been corrupted, you can use the special Recovery Console version of theBootcfg tool to fix it. Of course, you must first boot the system with theWindows XP CD and access the Recovery Console as described in #4.

To use the Bootcfg tool, from the Recovery Console commandprompt, type
Bootcfg /parameter
Where /parameter is one of these required parameters:

• /Add--Scans the disk for all Windowsinstallations and allows you to add any new ones to the Boot.ini file.
• /Scan--Scans the disk for all Windowsinstallations.
• /List--Lists each entry in the Boot.ini file.
• /Default--Sets the default operating system as themain boot entry.
• /Rebuild--Completely re-creates the Boot.inifile. The user must confirm each step.
• /Redirect--Allows the boot operation to beredirected to a specific port when using the Headless Administration feature.The Redirect parameter takes two parameters of its own, [Port Baudrate ] | [UseBiosSettings].
• /Disableredirect--Disables the redirection.

Issue: Fix a corrupt partition boot sector
The partition boot sector is a small section of the harddisk partition that contains information about the operating system's filesystem (NTFS or FAT32), as well as a very small machine language program thatis crucial in assisting the operating system as it loads.
If you suspect that Windows XP won't boot because thepartition boot sector has been corrupted, you can use a special RecoveryConsole tool called Fixboot to fix it. Start by booting the system with theWindows XP CD and accessing the Recovery Console as described in #4.

To use the Fixboot tool, from the Recovery Console commandprompt, type

Fixboot [drive]:

Where [drive] is the letter of the drive towhich you want to write a new partition boot sector.

Issue: Fix a corrupt master boot record
The master boot record occupies the first sector on the harddisk and is responsible for initiating the Windows boot procedure. The masterboot record contains the partition table for the disk as well as a smallprogram called the master boot code,which is responsible for locating the active, or bootable, partition, in thepartition table. Once this occurs, the partition boot sector takes over andbegins loading Windows. If the master boot record is corrupt, the partitionboot sector can't do its job and Windows won't boot.

If you suspect Windows XP won't boot because the master bootrecord has been corrupted, you can use the Recovery Console tool Fixmbr to fixit. First, boot the system with the Windows XP CD and access the RecoveryConsole as described in #4.

To use the Fixmbr tool, from the Recovery Console commandprompt, type
Fixmbr [device_name]

Where [device_name] is the devicepathname of the drive to which you want to write a new master boot record. Forexample, the device pathname format for a standard bootable drive Cconfiguration would look like this:

\Device\HardDisk0
