I have a single windows server 2003 Domain Controler. It handles DNS and DHCP as well. I have just purchased a Windows 2008 R2 server. I ran adprep on the 2003 and promoted the 2008 R2 to run as an additional domain controller. I want to retire the 2003 server. How do I transfer the dhcp role and, since I set up the 2008 as a DNS server and it has copied the DNS information from the 2003 server, can I simply point all other computers to the 2008 for DNS? Finally how do I demote the 2003 server and take it off the network?
