We have a few branch offices with a few people working in them, connected by a WAN. The offices do not justify having a full domain controller installed in them, but I wanted to localize DHCP traffic and provide a local DNS server for each branch office. Optimally, I would place a Win7Pro box on site, then run secondary DNS for the domain as well as that branch's DHCP.
What would you suggest as the best way to go about this? I want the DHCP server at the branch to update AD if possible. If a Microsoft solution does not exist I am open to other product suggestions.
