For most of the DNS world, a primary server gets its domain data from its own files, while a secondary server gets its domain data from some other server. A server that is primary for one domain can be secondary for another. Using a secondary server instead of multiple primary servers for a domain is simply a way to reduce the administrative work required to update the domain. When interacting with domain registrars, the primary server is the one you enter first, while the secondary is the one you enter second. They actually don't care which is which. Once domain data is loaded into both primary and secondary, the difference disappears. They are functionally equivalent. >Does a secondary DNS require a separate machine? If so, do we need to >purchase another license of QuickDNS Pro, or can we use our current one? Yes, a secondary is a separate machine. Under the terms of the license agreement for QuickDNS Pro, you can run two copies, providing that one copy is used only as a secondary (backup) for the other one. >How often do you restart your DNS servers? What time of day do you do so? Is >it automated, or do you do it manually? This is something others can answer. The official recommendation is, whenever necessary. I just restarted my local DNS server (also providing other services) for the first time in several months. The problem wasn't QuickDNS, but the TCP/IP stack, which had become corrupted. Nothing crashed, but the machine was deaf to the network. ____________________________________________________________________ Chris Buxton cbuxton@menandmice.com Men & Mice http://www.menandmice.com Makers of: QuickDNS Pro
