Thanks for the suggestion. I did verify that the DNS server is in proper working condition. I still have not been able to figure out what caused the problem, however, I did get the DBNDNS caching to work. This has at least gotten the network guys off my back, but it has added an extra layer for me to diagnose problems through in the future. :( Thanks again for responding, Chris Stackpole -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
