A former coworker shared the worst networking issue he ever encountered. He came in one day and his network wasn't working. He tried all the standard things, rebooting, trying different protocols, etc but couldn't figure it out. Pulled the cable out of the back of his computer and plugged it back in. Running around in circles for half a day. Finally he was going to replace the networking cable and found a tiny piece of scotch tape covering just a couple of the contacts.
