1.	Solve : How to kick out unauthorized accesses to network?
Answer» In our office, we ALWAYS FIND the strangers plug their PC into our network. Do you have any IDEA how to prevent this unauthorized access? Currently, if I find this strange PC, I will POWER on a "Testing PC" with the same IP address to kick out this PC but this is not efficient. Pls advise. Install a firewall. ZoneAlarm Free -- Free firewall - more user friendly Sygate Personal -- Free firewall - more configuration optionsAnthony: I take it this is a wireless network and not an Ethernet LAN? DOC
