Replace two Active Directory Servers keeping the same IP?

view story
linux-howto

http://serverfault.com – I have two AD servers: 192.168.1.1 and 192.168.1.2. One is a Windows Server 2008 (non-R2) and the other is R2. Both are AD servers for our local network. It's a simple network, 30 clients. Now I need to replace the hardware of these two servers for newer, most powerful ones. But the server NAMES and IP ADDRESSES must be the same after the replacement. What should be the best path to follow and to keep the AD database? (I cannot change the IP address when the machine is an AD server) Update I'm thinking in: Demote 192.168.1.2 Remove it from domain. Add the new server into domain with t (HowTos)

Stories similar to Replace two Active Directory Servers keeping the same IP?

I have a hub-and-spoke network with a central office with the servers at one location, and several smaller offices (with no servers) at other locations.

Each location has a sonicwall firewall device.

I have two Windows Server 2008 R2 servers which act as both Active Directory primary domain controllers and DNS servers on my network. Both computers have WINS installed and are the primary and secondary DNS servers for all of the computers on the network.

When I enter a URL such as http:// server.mydomain.local, the server's IP resolves properly.

I have searched high and low for a solution to this problem.

I have multiple servers running 2000, 2003, 2003 R2 and 2008 R2 using active directory and all on the same single domain.

The servers run showing the network profile as Domain which is fine and correct. However, when a windows update is installed the server changes the profile to unidentified once it has rebooted.

I have two database servers(redundancy), one web server and two windows servers 2008 (ADDS redundancy). I set up this network for university assignment. What would be the best way to design Active directory for this. How database server and web server will communicate with active directory.Plz explain it if possible as I am still a novice in this area.

Here's a quick summary of the environment I support: we have a domain (domain A) that has about 20 client computers. The domain server for this domain and all the clients sit within the network infrastructure of a larger domain (domain B). All the computers get their network settings via DHCP from domain B's servers.

I have 4 servers running windows server 2012.

I have one of the setup as my domain controller, for let's say domain.local

Obviously when I installed this it added the DNS server and this was as expected. I then proceeded in joining my other servers to the domain and all went well, I also set the DNS to only respond to requests coming in on the internal network's NIC.

I have a windows server 2003 as a PDC ("server 1"). I am attempting to take it offline once I get several issues cleared up. I have two other windows server 2008 servers that have been promoted as DC's ("server 2" and "server 3").

I have 3 computers, two of which are servers running Windows Server 2008 and another running Windows 7.

One of the servers has the following roles installed; Active Directory, DHCP and DNS. The other server has a Terminal Server role installed.

This Saturday evening we're going to be replacing our existing Windows Server 2003 domain controllers/dns servers with Windows Server 2008 R2 domain controllers/dns servers. The current forest and domain functional levels are Windows Server 2003 and I've already run adprep /forestprep and adprep /domainprep /gprep from the W2K8R2 media on the existing schema operations master.
