I have 4 sites with 3 domain controller that do not do DHCP and role isn't installed on any of the dc's. All of our cisco switches are controlling dhcp and would like to know process of implementing dhcp on our windows 2008 r2 servers at each of our sites instead of having switches control this process.
My plan is to implement another domain controller at our 4th site. Also would like in the event that computers that request dhcp lease at a site that a dc goes down they can request from another site as well.
Thank you,
