Thanks for the suggestions, Dan.
Had a look at my router's setup and couldn't see any options to have it assign DNS addresses to clients (Netgear RP114 Cable/DSL router). Had a quick bash at assigning DNS servers manually like you suggested, but naturally my internet connection promptly died, so I did what I normally do in these situations: showed no fear, backed out slowly and ... ran like hell to my saved prior configuration!
I know what all these acronyms stand for (I've even done courses with networking components), and have been using computers fairly proficiently since my mac plus lo those many years ago, but configuring a network is still so much voodoo to me. (I can't even successfully share a usb printer between the desktop and the portable ... even with Rendezvous!) Enjoyed the article, though. Maybe one day ...
and ps. Just wanted to tell you how glad I was that Zeldman threw his weight around and convinced you to keep Hivelogic going - it broke my heart to see it go down!
