Teckedd, I too have the same issue using Cisco ip-helpers, 2008R2 DHCP Servers, and Win 7 clients on both wired and wireless. Are you saying that Win 7 on startup is requesting and expecting back a Unicast DHCP Offer by default, and even though it gets a Unicast offer back, it still drops it, and that this is the Microsoft Bug, which only occurs in the Public firewall profile before it transitions to the Domain profile, and that the Domain profile doesnt drop the Unicast offer that it asked for.
