So, I was thinking that I would write a script to transfer some DHCP scopes from one machine to another. Well, wouldn't you know... there is already a tool to do that, and I didn't even have to install software, just read a little article...

I have Windows Server 2003. So here is the pertinant part for me:
Use this command to export all scopes from the source machine:
netsh dhcp server export C:\dhcp.txt all
Install the dhcp server on the new machine and run this import command:
netsh dhcp server import C:\dhcp.txt all
After that authorize the dhcp server and that´s it!
Quick and easy.
