Hello all and thanks for having a great resource.
I have a complicated question to ask and hope someone has experience that can help.
Current Situation: My network has a W2K3 server running Active Directory for a no longer used AD Domain. I would like to get rid of this server but it is also running DHCP for my campus network. The previous engineer used the entire class B address as the scope and then excluded addresses that he wanted to use for static addressing. I would like to change this as I do not believe it is the correct way to do it.
New Situation: I have a W2K8R2 server running as a Domain controller for the AD domain that we are currently using. The subnet for the campus is the same. I have created a DHCP scope using 10.50.7.1 - 10.50.8.254 from the range 10.50.0.0 as the scope of addresses. I have also updated the DNS and other options to match what is currently needed versus what was needed in the past. I have not yet authorized the new DHCP server. The servers are on the same subnet.
Question: Is it just as simple as turning off the DHCP server service on the old server and Authorizing the new DHCP server and all is well? Will the clients get an address from the new DHCP server when they cannot reach the old one?
If not, what would be the proper way of moving to a new DHCP server without migrating the current settings from the old one?
Thanks for any input.
