I have a network which is based on a number of servers running FreeBsd 6.0 serving Win XP work stations. (yes I know but..) The network is large enough to use DHCP and DNS for the internal network, I have setup a DHCP server with a Dynamic DNS (Bind 9) on one of the servers. That server is handling the LDAP side of the domain. There appears to be a fair bit of DNS Traffic which leads to a secondary DNS being required to take some of the load as DNS lookup are slow. The question I have is should I just setup a cashing DNS on another server using the primary as a forwarder or even several servers eg the mail server and the secondary LDAP server, or should I setup a proper secondary DNS using my ISP as a forwarder with dynamic updates from the primary. Sorry if this is a bit vague, but I have no experience in this area. Rob
