I've seen following scenario more than once while at client sites: Suddenly one of the servers reboots. IP conflict alert is displayed on the monitor, but sometimes it's seen/noticed before the reboot, sometimes not. Inspecting eventviewer logs reveals that IP conflict has caused this and it shows the offending MAC address. Since the IP conflict alert is displayed on both ends, the guilty party usually quickly changes his/her IP setting and reboots, hoping nobody had noticed. But you can easily find out which IP is currently associated with that MAC address and, therefore, the guilty party. It's usually either a visitor (e.g. somebody from Arthur Andersen doing a financial audit) or a user returning from a business trip, and their laptop for whatever reason had a static IP that happen to coincide with one of the servers. Now, depending on what was running on the server, this sudden reboot could be benign or could be a big problem. In one instance, a server running ADP/Oracle got hit and they spent hours & hours reviving the system. Now to the point: One of the reasons I setup VLANs is to separate the servers and the workstations to prevent this type of thing from occuring. Just make sure that all RJ-45 jacks that users could plug their laptop or desktop into are wired to the switch ports that belong to the workstation VLAN(s). And, when you have VLANs, you must route between those subnets. And routing (layer 3) is slower than switching (layer 2). Depending on the size of the enterprise, they may or may not experience severe performance hit due to heavy inter-VLAN routing. To compensate in such case, add equipment that does layer 3 switching.
