IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY
With Windows 2000 Active Directory, circular logging is the default for maintaining transactions to the store (Ntds.dit). These transactions are recorded in the current log file (Edb.log), which is 10 megabytes (MB) in size. Windows 2000 (specifically, Esent.dll) can create a new log file when the current one becomes filled. This is known as non-circular logging. Windows 2000 can also overwrite the oldest file when the specified number of log files is reached. This is known as circular logging.

MORE INFORMATION
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To change the Windows 2000 default behavior of circular logging to non-circular logging, locate the following key using Registry Editor (Regedt32.exe):

"HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters" Modify the following value: Value Name: CircularLogging

Data Type : REG_DWORD

Data Value : 0x1 - Circular logging enabled

Data Value : 0x0 - Circular logging disabled

Default Value (if not present) : 0x1 - Circular logging enabled NOTE: This value may not be present. Add the value if this is the case. Additional query words:
