Rebuilding damaged a DHCP server (Windows server)

I want to know how to rebuild damge DHCP server if incase my server got damage . I don't want that the extensive reservations, and everything disappears before you find one or two hours configuration. any suggestions?

You can avoid this by using a single command.

• To save your DHCP command prompt type:
  
  netsh dhcp server dump
  
• If you are not at the server, type in place:
  
  
  netsh dhcp server IP address dump
  
  
• Many lines of configuration information displayed on the screen:
  Save them in the direction an ASCII file:
  
  netsh dhcp server dump> dhcpbackup.txt
  
  
• Then when the DHCP server goes down, all you have to do is to put the DHCP Server service on another computer, copy your backup file and use netsh exex, as follows:
  
  netsh exec dhcpbackup.txt
  
  
• You can not get information leases under way, but you get all other information: classes, options, extensive reservations, etc ...

Thanks I'll try this.
