I'm wondering if I can install CPNR 8.1 on a standlone server to provide DHCP, DNS, TFTP and SNMP server capabilities to a single campus network? When I read the different guides out there, I'm getting confused about the need for a regional cluster and local cluster and all that. I don't need a cluster. All I need is a single server handling these services for my network. Can I use CPNR here? If so, in what mode to I have to install? Local or Regional?
