Espectr0 writes: We are an insurance company with about 600 client machines dispersed in 20 cities in our country. Our server infrastructure is mostly centralized on one city, with servers running Windows 2003 Server and Windows 2008 Server. We just want to migrate Active Directory from 2003 to 2008. Not everyone of our clients are using DHCP, which we want to force with group policy with this migration. Our clients are 80% windows xp pro sp3, with the rest being windows 7 pro. So far we have found this link and this one. Any good tips?
