We are a small business (~100 emp) with a creaking server running AD, Exchange 2003 and more. We need to upgrade the hardware and it has been proposed to put Win Svr Std 2008 on one new server with AD on the physical server and Exchange 2010 on virtual server. But from what I see this is not a recommended configuration.
I can see two options: 1) use Win Svr Ent 2008 and put AD on one virtual server and exchange 2010 on another (the extra virtual servers for Ent edition will always come in useful) 2) buy 2 independent servers and put AD on one and exchange 2010 on the other
There must be many many small businesses running AD & Exchange. Can anybody tell me what is an optimum configuration in terms of performance and cost?
