We are looking at replacing our 1st domain controller\nwith a new server. The current DC is our pdc emulator\nand Start of Authority for everything. It is our main\nDNS server as well. It's OS is Windows 2000. We want to\nreplace it with Windows Server 2003. We are currently in\nWindows 2000 mixed mode. We have a second DC which is\nour Exchange Server. We have about 10 other domain\ncontrollers, mostly at remote sites. How complicated is\nthis going to be? Are there resources on how to do it?
