Hi, Have downloaded the BRS demo environment 4g (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=726f943e-d107-4b4d-a86e-dfb605e30ce5) - and when starting Madrid there is a bunch of Exchange services that do not start, and no Forefront Protection services start. On further investigation I have found that one of the dependant services on Madrid is just not there - the Netlogon (Workstation) service. So no other dependant services will start. has anyone experienced the same problem? how does one resolve this? thanks
