  • Start the command prompt (cmd.exe)
  • netsh
  • DHCP
  • server
  • export W2K3DHCP all or export W2K3DHCP <scope, e.q.>
  • Copy the export file to the other (W2K8) server
  • stop the DHCPSERVER net stop DHCPSERVER or using services.msc
  • delete the DHCP.mdb (located c:\windows\system32\dhcp)
  • start the DHCP server
