I have already caused a half day of outage and I feel terrible. Please, if anyone has anything to offer, help. I can call the local IT guy and try to work things out with him tomorrow morning, but want to get all the information I can first. I now think that my action caused the dsl connection problem. I did some more googling, and found this old post: I've been watching the network connection by trying to log into the local outlook server, but the connection has been down all weekend. I tried to look up variations on 'Wireshark making network go down,' but the searches returned nothing useful. Our local IT guy say something online about an internet outage in this area.

We called provider 2 and they said the problem was at provider 1. We called the local provider, they said that a problem was at another provider. That did not change the dsl connection status. We called our local IT guy, he asked us to power cycle the router. Our local network appeared to be fine, and our router said the dsl connection was down. I ran Wireshark all day, looking at the network traffic. On thursday, I downloaded and ran Wireshark. As the only on site team member with any general IT knowledge, I have become the guy that's expected to take care of computer problems.
