I'm working with a contractor, who was hired by one of our employees. He's having trouble meeting his deadlines and offered the following in explanation: "A technician completely screwed up all of our IP addresses when he was trying to put a color printer demo onto our network. What he did was assign the printer a static IP address, well what he failed to check was that our phone system and network all run static IPs, so when he put it on line, he caused conflicts that rippled through the network that one by one began to cause conflicts and began taking everything off line. He started before anybody was in the office. I would compare it to a slow poisoning of the network." Now, I guess someone might run a LAN with all static IPs if they were masochists, but assigning a conflicting IP to a printer, while stupid, shouldn't hurt THAT much, could it? Maybe they conflicted with the domain controller which was running DNS... But isn't preventing such problems part of a competent IT pro's job? I think if I'd let something like that happen I would have made up a story about A-Rab terrorists or something. Wanna kill these ads? We can help!
