My school uses a T1 connection provided by our local phone company (verizon). In my network class we use a computer running windows 200 advanced server to assign ip's (192.198.x.x) to the computer in the classroom. This cuts down the hassel of getting an ip for each computer in the class from our lovely network admin. Long story short someone too the password protection off of the server leaving it open to anyone to play with. Another person got into the server and changed the subnet mask from 255.255.255.0 to 126.96.36.199. This caused the server to not only try and assign ips to the computers in the class, but anyone using Verizon internet services in our area (DSL, T1, and dialup). It took a day of slow service for verizon to figure out where the problem was comming from. When they did figure it out they cut off the internet to the whole school! Now the network admin for our school shut off the internet to the room in an attempt to be the biggest...well you get the idea. Despite this setback we have a few plans to get the internet back to our little LAN. I just thought I would share this story, since I though it was pretty funny (even when people were questioning me about wether or not I caused this mess)!
