启动报错：

A Windows 2008 R2 Domain controller started coming up with with the following error, coincidentally at the same time one of the drives failed in the raid array

STOP: c00002e2 Directory Services could not start because of the following error: A device attached to the system is not functioning.

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

处理步骤：

1. Restart the server and press F8 key, select Directory Services restore mode.
2. Log in with the local administrator username and password
3. Type: cd \windows\system32
4. Type: NTDSUTIL
5. Type: activate instance NTDS
6. Type: files
7. If you encounter an error stating that the Jet engine could not be initialized exit out of ntdsutil.
8. Type: cd\
9. Type: md backupad
10. Type: cd \windows\ntds
11. Type: copy ntds.dit c:\backupad
12. Type: cd \windows\system32
13. Type: esentutl /g c:\windows\ntds\ntds.dit
14. This will perform an integrity check, (the results indicate that the jet database is corrupt)
15. Type: esentutl /p   c:\windows\ntds\ntds.dit
16. Agree with the prompt
17. Type: cd \windows\ntds
18. Type: move *.log c:\backupad   (or just delete the log files)

This should complete the repair.  To verify that the repair has worked successfully:

1. Type: cd \windows\system32
2. Type: ntdsutil
3. Type: activate instance ntds
4. Type: files        (you should no longer get an error when you do this)
5. Type: info       (file info should now appear correctly)

I then rebooted and windows started normally
