This is great but what about DA and ISA Server/Forefront TMG? What are the implications? Do we still need to have an ISA is place if we have Win 2k8 R2 DCs and Win 7 clients? Right now, I'm publishing OWA, OA, MOSS 2007, OCS 2007 to my remote users via ISA. What would happen if I upgrade my DCs to Win 2k8 R2 and deploy Win 7 to my end users?
