Defrag AD Using Ntdsutil to Defrag AD Need to clean up AD? Ntdsutil gets the job done May 26, 2003 Mark England | Windows IT Pro EMAIL Tweet Comments 2 Advertisement If you run a Windows 2000 network, you most likely use Active Directory. AD, like most other directory services, uses a database—in AD's case, a version of the Microsoft
Difference Between Online And Offline Defragmentation Active Directory
Extensible Storage Engine (ESE)—to store information. AD is the heart and soul of Win2K, so you need to take extra care to ensure its health. Periodically using the Ntdsutil utility (ntdsutil.exe) to perform an offline defragmentation can help you achieve this goal. Get to Know AD and Your Defragmentation Options Before you begin working with Ntdsutil, get to know the key AD database files—edb.log, ntds.dit, res1.log, res2.log, and edb.chk—all of which reside in \%systemroot%\ntds on a domain controller (DC) by default. During AD installation, Dcpromo lets you specify alternative locations for these log files and database files, as Figure 1, page 76, shows. The best practice for a Win2K DC is to install the OS files, transaction logs, and database files on separate spindles. The most common approach is to install the files on separate mirrored drives (i.e., RAID 1). Any change to AD triggers a write operation, which causes ESE to write all changes to both the database file and the log file. AD periodically flushes the log file as the OS commits sets of database updates

lab environment my Windows 2008 R2 Domain Controller VM did not start. When booting the VM I got a BSOD with a STOP error: 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. This was my only Domain Controller and no backup so I had to solve this problem. Troubleshooting steps: 1. Boot into Directory Services Restore Mode (F8) 2. NTDSUTIL: activate instance NTDS files Error: Could not initialize the Jet engine: Jet Error -501. Failed to open DIT for AD DS/LDS instance NTDS. Error -2147418113 quit 3. ESENTUTL /g C:\Windows\NTDS\ntds.dit ESENTUTL result: successful (no DB corruption) 4. ESENTUTL /p C:\Windows\NTDS\ntds.dit ESENTUTL result: successful (no DB corruption) 5. Event log: Error 1003: Active Directory Domain Services could not be initialized. The directory service cannot recover from this error. Restore the local directory service from backup media. Error value: -501 JET_errLogFileCorrupt, Log file is corrupt Error 465: NTDS (2156) Corruption was detected during soft recovery in logfile C:\Windows\NTDS\edb.log. The failing checksum record is located at position END. Data not matching the log-file fill pattern first appeared in sector 6697 (0x00001A29). This logfile has been damaged and is unusable. Error 454: NTDS (2256) Database recovery/restore failed with unexpected error -501. 6. Rename edb.log to edb.log.old and restart system Result: same STOP error Solution to this problem: rename all *.log files in C:\Windows\NTDS folder and restart system.
