Need to assign multiple DNS servers via DHCP

I have recently implemented a second DNS server in our local domain with the intention to use the secondary server to filter traffic via OpenDNS, so the idea is to assign specific computers to use the secondary DNS server, however I have not seen an option via DHCP to assign a different DNS server via reservation, is there a different method that I can tell DHCP to assign a different DNS only to specific computers? Any help will be appreciated.

You can achieve this by putting those computers in a seperate OU and having a gpo add the DNS server ip of your preference.

Which version of Windows is your DHCP server running? In 2012 R2, the only version I've got available at the moment, you can do exactly that with a reservation. Just right-click the reservation in the DHCP console and select Configure Options.

I don't know if that's a 2012 R2 feature, though, or if it's available in older versions as well.

DrDave,
Are you positive about being able to assign DNS settings under the Windows 2012 DHCP scope? It not an option on Windows 2003 or Windows 2008, at least I have not seen it.

Yep, got it running in a VM right now. Here's a screenshot of the Reservation Options window that appears when you right-click a reservation and select Configure Options:

BTW, I noticed I had to click on the reservation itself in the left pane of the console before Configure Options was available in the right-click menu. Just a console glitch, I suppose.
