We have a PDC (Schema Master) that is a Windows Server 2003 machine on a Windows network. We have one domain only. This server is our PDC, Schema Master, NTP, roaming profiles server, ect. We have a new Windows 2008 server that we want to take over all of these roles. We have made it a Domain Controller and Global Catalog server but we are already having issues with the NTP role. Any assistance offered with steps links on how to transfer the roles above and the roaming profiles over would be greatly appreciated.
