I'm looking at a RFQ for taking over a company's infrastructure management. I'm fuzzy on details (am preparing an email back to them to clarify some things), but it sounds like they want ALL of the hardware in their office out. The things they have running are relatively standard (AD, Exchange, SQL Server, SharePoint).
My question revolves around having a remote AD controller. I know there are tons of situations where you have branch offices that use the home office's AD controller via site to site VPN. It just feels a bit ... off to relocate this ENTIRE stack to a remote site (either our offices, or, more likely, a local colocation facility). There's obviously going to have to be some kind of device remaining to do DHCP at a minimum since their current AD server handles all DHCP and DNS responsibilities.
Does this configuration seem legit to others?
