I guess my brain in not working right today so I'll ask the Experts.
Installing new DC into existing DOMAIN on a different site/segment.
Primary (Default Domain) is 192.168.34.xxx has its own DC DHCP/DNS
Factory Domain in 192.168.36.xx has its own DC DHCP/DNS
I am going to demote current 2008r2 DC which is the DC that hands out DHCP and is DNS.
What steps do I need to do to make sure things go right...
Users get DHCP from new DC, DNS records, Etc...
