| Description | "The DHCP service failed to restore the database. The following error occurred: %1" |
| Event Information | According to Microsoft : Cause : This event is logged when DHCP service failed to restore the database. Resolution : 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. If DHCP Manager was used previously to perform a backup, you can obtain the backup copy of the server database file located in the %SystemRoot%\System32\Dhcp\Backup folder. You can also restore the Dhcp.mdb file from a tape backup or other backup media. To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority. To restore a backup copy of the DHCP database: 1.Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as Administrator. 2.Type net stop dhcpserver, and then press ENTER. 3.Type md c:\olddhcp, and then press ENTER. 4.Type move %SystemRoot%\system32\DHCP\*.* c:\olddhcp, and then press ENTER. 5.Type del %SystemRoot%\system32\DHCP\Dhcp.md, and then press ENTER. 6.Type copy%SystemRoot%\system32\dhcp\backup\jet\new\dhcp.mdb%SystemRoot%\system32\dhcp\dhcp.mdb, and then press ENTER. 7.Type net start dhcpserver, and then press ENTER. Verify To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority. To verify that backup and restore was successful: 1.In the DHCP snap-in, right-click IPv4, and then click Properties. 2.Navigate to the DHCP database path at %SystemRoot%\System32\Dhcp, and then verify the presence of recently created files. 3.Type net start dhcpserver, and then press ENTER.
