When you try to start a Windows 2000 domain controller, you receive:

Lsass.exe - System Error

Directory Services could not start because of the following error: There is not enough space on the disk. Error Status: 0xc000007f. Please click OK to shutdown this system and reboot into Directory Service Restore Mode, check the event logs for more detailed information.

The event logs contain:

Event ID: 1393                              Attempts to update the Directory Service database are failing with error 112.                               Since Windows will be unable to log on users while this condition persists,                               the Netlogon service is being paused. Check to make sure that adequate free disk space                              is available on the drives where the directory database and log files reside.                              Event ID: 428                              NTDS (272) The database engine is rejecting update operations due to low free disk space on the log disk.                               Event ID 2013:                              The <Drive:> disk is nearing Capacity. You may need to delete some files.

You are running low on disk space or you have performed mass directory imports.

Make sure that you don't have old EDBxxxxx.log. files left over from NTBackup.

NOTE: Upgrading to Service Pack 2 will prevent NTBackup from leaving EDBxxxxx.log files.

To workaround this issue:

1. Press OK so that the computer will restart.

2. Press F8 when the Boot menu appears.

3. Boot to Directory Services Restore mode and log on with the Directory Services Restore mode administrator account and password (assigned during DCPromo).

4. Locate the drive containing the directory and log files, generally the NTDS folder of %SystemRoot%.

5. Delete any old EDBxxxxx.log files.

6. Free any other space on the drive that you can.

7. Restart the computer.
