DHCP

One of my customers asked me to dismiss an old Windows 2003 R2 server which is running the DHCP service for a bunch of workstations and to replace it with a new Windows 2012 server we installed last December.Seen the fact that this DHCP service is configured with many options and a lot of reservations, and that I am totally lazy about recreating all these settings manually, I found a way to dump its configuration to a text file and to import it back to Windows 2012.Let's start exporting the DHCP database from the server that...
