Im facing a problem here in my network. Due to an auditory, some years ago I had physically split my network in 2, with 2 windows domains. One network is for administrative tasks: accoutning, etc. The second, for the educational side of my office. Here is the problem. When we were ordered to do so, we didnt took into cosideration that we didnt and we would never have the resources to keep 2 domains operating with some decent reliability. For example, I just have one domain controller for each domain. I do not have and I wont be allowed to buy more domain controllers. When one domain controller breaks, or windows fails (yes, I have seen Windows 2000 shutdown and never wake up again without any cause) the whole domain is lost. So, Im planning to join both domains in a single one, but I need some sort of protection for the PCs running accounting tasks so I can please the future auditors. what can you recommend?
What do you have in the rest of your network? In particular, how did you split your network? Are they actually physically separate, or are you using a firewall or layer3 switch to separate them? Do you have a spare PC that you into which can put an extra NIC? If so, pfsense could be your friend, or some other free firewall package, by allowing you to deny traffic from the (relatively) untrusted traffic. I'd also study up on securing your DCs. Lots of good literature out in the world for that.
