Here my favorite. About 10 years ago at a customer site a user was had a non-IBM token ring card, the manufacturer of the NIC wanted to prove that it could make a faster T/R card than IBM so they set the bridge priority bit on every packet. Then to top it off the user had installed a screen saver for their workstation and had the files installed to their home directory on the server. It was an early version of After Dark that constantly access the hard drive. Whenever the screen saver kicked in it brought the network to it's knees.
