Event Message:

The DHCP service encountered the following error when backing up the database: code

Source Event Log Event ID Event Type
DhcpServer System 1016 Error


This error occurs when you move the Dynamic Host Configuration Protocol (DHCP) database and its backup directories from the default location. When the DHCP service is initially installed, its database is stored in the Systemroot\System32\DHCP folder, and the backup folder is set to Systemroot\System32\DHCP\Backup\Jet. The DHCP database tracks all attached database directories and files in the System.mdb file. If the database and backup directories are moved, the backup fails. It does so because it tries to back up the database from the old and new locations but cannot find the database file in the old location.

User Action:

Copy the original Windows 2000 system.md_ file from the Windows 2000 compact disc to your hard drive. Then, run the Systemroot\System32\Expand.exe program to expand System.md_ to System.mdb. Next, copy System.mdb to the new database location.
