Hi everyone! Next month I have to do an IP Address Range change on the network here. I have approx 200 clients and 3 DC's. I would really appreciate any help / step-by-step instructions that you can offer. I have already searched out anything with static addresses so I am not expecting any big headaches there - I'm more concerned with the actual change on the three Servers and what order I need to do things in. Any advice would be greatly appreciated, Thanks, Charlie.
