Active Directory (AD) will shut down the Windows 2000 Server system if it runs out of space. If you’re very low on hard disk space you can add a new hard drive and move AD files to it.

Keep in mind before you actually move any of the AD files, you need to create a backup. After you create a backup, follow these steps:

1. Restart Windows 2000 Domain Controller in the Directory Services Restore mode.
2. Log on as the local administrator with the password you specified when you installed AD.
3. Open the command prompt and run Ntdsutil.
4. At the Ntdsutil prompt, type files and press [Enter].
5. Type move DB to x:\path, where x:\path represents the full path to the directory that will hold the AD database.
6. To exit, type quit and press [Enter] twice.

To move transactional log files, in step five, type move logs to x:\path instead of move DB to x:\path.
