We currently have an old 2000 server that functions as a domain controller. Finally got a new server running Server 2012 standard. Since I don't want to change the the IP address range and subnet. I thought i should first dis join all computers and the other server( Server 2008 Standard running remote desk top services, print service) and just bring up the new server with the existing ip range and same settings for DHCP,DNS and rejoin all the existing machines to the new domain. I'm trying to avoid having to re setup router and switches, wireless access point and printers and vpn tunnels(sonic walls at other sites.. Do you foresee any problems I might face by taking this approach? the current domain controller(server 2000) is the only server handling authentication, DHCP, DNS. and remote access..
