192.168.1.1 is the default used by a *lot* of SOHO NAT equipment, not just LinkSys. Almost certainly, somebody has taken their bitty-box home router with the built-in four-port-switch, and plugged it into your LAN to get some extra ports, not even knowing they're screwing up your LAN in the process. Assign 192.168.1.42 as an IP address to a test machine, and ping 192.168.1.1 from the test box. Then check the ARP table to get the MAC address of the rogue device. The OUI part of the MAC address will tell you the brand of device. Then use your managed switches to track down the port the rogue device is connected to. If you don't have manged switches, use a non-Microsoft ping tool to flood ping the 192.168.1.1 device. Follow the spastic link lights to find the port. -- Ben ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
