A bitmask that determines the characteristics of the Net Logon debugging log, Netlogon.log.

For detailed debugging of the Net Logon service for Windows 2000, set the value of this entry to 0xFFFF. To debug replication problems between Windows 2000 and Windows NT 4.0 and earlier, set the value to 0x80FFFF. On computers running Windows NT 4.0 and earlier, set the value to 0x2080FFFF.

Change method

To change the value of DBFlag, use Nltest, a command-line tool for Net Logon administration in the \Support\Tools folder of the Windows 2000 operating system CD. At the command line, type:

Nltest /DBFLAG:<Hexadecimal value>.

Do not edit the registry.

Activation method

To make changes to this entry effective, you must restart the computer.

Note Image Note

You can enter values in decimal or hexadecimal format. All hexadecimal values must be preceded by the "0x" characters.

Netlogon.dll is fully supported in Windows 2000. In Windows NT 4.0 and earlier, the debugging log is supported only by the internal debugging versions of Netlogon.dll. To use this functionality on Windows NT 4.0 and earlier, obtain a debugging version of Netlogon.dll from Microsoft Product Support Services at http://support.microsoft.com.
