Restore the DHCP Database
Applies To: Windows Server 2008
You can use this procedure to restore a DHCP database.
Membership in the Administrators group or the DHCP Administrators group on the DHCP server is the minimum required to complete this procedure.
To restore the DHCP database
In the console tree, click the applicable DHCP server.
On the Action menu, click Restore.
In the Browse For Folder dialog box, select the folder that contains the backup DHCP database, and then click OK.
Only a DHCP database backed up from the same Windows server version can be restored. Restoring a DHCP database from a different Windows server version is not supported. To migrate a DHCP database from one Windows Server version to another, use the netsh export/import command.
To restore the DHCP database, the DHCP service is temporarily stopped. When it is stopped, DHCP clients are unable to contact the DHCP server and obtain IP addresses.
Only DHCP databases from the same language version can be restored. For example, a DHCP database from DHCP server running an English language version of the operating system cannot be restored to a DHCP server running a Japanese language version of the operating system.
