I got a panic call from one of our bigger clients this morning - NOTHING IS WORKING! I look and neither their DC or their SQL server is on the internet, and no one can connect to their practice management application that runs on the SQL server. Rebooting the servers and firewall didn't work. I could remote into the firewall, but couldn't RDP to or ping anything on the network.
So I drop everything and go. Once onsite, I get the vital piece of information: The painters were here yesterday and moved some furniture around. So I walk through the various rooms looking for something out of place. I wasn't disappointed. There was a Sonos Boost unit on one of the desks. "When did you get that system?" "Oh, a couple of months ago - it works great!" "I didn't call you because it was SO EASY to install - my son helped me!"
.
I take a look and there is a single network drop for that desk. Underneath the desk is a new 4-port switch installed with 4 cables coming out of it and all of it's lights flashing wildly. One cable goes to the wall jack, one to the computer, and TWO to the Sonos box. The Sonos box has two network ports so you can put it inline with an existing device, but someone decided to connect BOTH of those ports to the new little network switch. This created a loop which took down the entire network.
Easy fix removing the errant cable and rebooting a couple of things - hopefully my bill will be a good reminder to call and ask before plugging new things into the network, but I doubt it.
