JSI Tip 2534. The Windows 2000 default DHCP BackupInterval is incorrect in online help.

The DHCP Database Files section in the DHCP online Help states that the default DHCP BackupInterval is 15 minutes.

The correct default is 60 minutes:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DhcpServer\Parameters

BackupInterval is a REG_DWORD value with a range from 1 to 71582 minutes.

A related entry is BackupDatabasePath, a REG_EXPAND_SZ value, that specifies the folder where the backup copy of the DHCP client database resides.

NOTE: The backup can be on a different local drive, to facilitate recovery.
