Hello community, I just recently provisioned a pair of Windows 2012 R2 Domain Controller/DNS Servers, transferred FSMO roles etc and need to update my DHCP scopes to point to new DC's before decommissioning my old Win2008 DC's.
Can someone kindly confirm my commands/syntax as outlined below:
Point to new DNS Servers:
config t Router(config)# ip dhcp pool <Pool Name> Router(config-dhcp)# no dns-server <old IP Addr #1> <old IP Addr #2> Router(config-dhcp)# dns-server <new IP Addr #1> <new IP Addr #2> Router(config-dhcp)# exit wr mem
Update Name Servers info on end routers:
config t Router(config)#no ip name-server <old IP Addr #1> Router(config)#no ip name-server <old IP Addr #2> Router(config)#ip name-server <New IP Addr #1> Router(config)#ip name-server <New IP Addr #2> wr mem
Where <new IP addr #1> = 192.168.1.236 Where <new IP addr #2> = 192.168.1.237
