Add any new devices to the network lately? The reason I ask is because I tried hooking up a Cisco WET200 Wireless Bridge a couple weeks ago and within 30 min it will cause a couple of my 2950's to start dropping and rebuilding their ARP tables. And of course during the 30 sec they are doing that all connectivity on those switches is down. So far they haven't been able to explain how that could happen especially since the AP's the bridge are connecting to aren't even plugged in to the switches in question.

So anyway, we lost all connectivity around noon at our main office. After some various checks on the servers, I try to ping some of them from my workstation and every so often I get a reply but mostly its timing out. I go to our wire closet and shut off the UPS that all our switches are on, bring them back up and low and behold everything is working again. Anyone have any idea what one of these switches was doing to bring the network to its knees? If it happens again I will restart them individually to see which one caused the drama. Network was down for 45 minutes, not happy.
