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?
Yes you should be able to point your computers to 2008 for DNS and to transfer your DHCP follow this http://blogs.technet.com/b
