I have a customer with a single 2008 R2 domain controller and they're running a mixed client environment with PCs and macs. The domain is currently a .local domain but it's causing endless problems with the macs because of bonjour services (which they want to keep using - for various reasons). So, we have to change the domain name. I was considering a domain rename but understand it's not possible if CA services are installed. Any suggestions on the best way to tackle this short of building a new domain? They only have 15 end users. Looking for the easiest way forward.
