Backup and Restore DHCP server configurations

In the previous DHCP server learning process, we know that some configuration operations are still troublesome. Here, we need to back up and restore the DHCP server configuration information. The specific operations are also summarized below. In network management, backing up some necessary configuration information is an important task, so that when the network fails, the correct configuration information can be restored in a timely manner to ensure the normal operation of the network. DHCP server configuration is no exception. In the Windows 2003 Server Operating System, the DHCP server configuration backup and restoration functions are also provided.

Step 1: Open the DHCP console, expand the "DHCP" option in the console window, select the created DHCP server, right-click the server name, select "backup ". 1)
