I have a client who I am working with to design a cost effective solution for their servers, especially from a microsoft licensing standpoint.
I would like to consolidate as many server roles as possible into these couple of servers. I know that I need 2 dc's at minimum to ensure that users can function within the domain in the event that one of the DC's fail. The problem is that best practice is to not combine the ADS role with other roles. I'm hoping not to purchase the CAL's for two severs where the only role is ADS. I don't want to shortcut this. Are there any roles that are safe to combine with ADS? I would imagine that terminal services and web services are an obvious no? Any suggestions are appreciated.
