Event InformationAccording to Microsoft :
Cause :
This event is logged when DHCP service failed to initialize the database.

Repair database and restore from a known good backup
If the DHCP server database becomes corrupted or is lost, recovery is possible by replacing the server database file (Dhcp.mdb), located in the %SystemRoot%\System32\Dhcp folder, with a backup copy of the same file.

1.Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as Administrator.
