I have a medium size LAn of 50 nodes. use internet connection sharing to distribute the broadband internet link on my backup server. Use static IP addresses for the workstation. Some one somewhere in the LAN is configuring his system to the same 192.168.0.1 to conflict with the server, hence no one can browse.
How can this be prevented? How do I know which computer/workstation has the MAC address on the event viewer message?

why not use DHCP to help avoid this issue?

If DHCP is not an option then you should restrict everyone's privilege so that they cannot change the network settings. What OS are the workstations using?

A good suggestion, when i use DHCP, the workstation will not browse. The workstation are mixed OS, win 98, 2000pro, xp pro. I do not have budget to buy proxy server software.

To identify the culprit, you can run winipcfg (Win98) or ipconfig /all on each client to find their MAC address.

Recommend that you document each client's configuration while you're at it. Probably will come in handy later. It is a good practice to document settings when first configuring a client PC. Keep a spreadsheet or database with each client's info (IP address, MAC address, OS, NIC, ID number, location, user, etc.)

These are recommended practice before configuration, now it has been configured, scattered in five floors of two buildings, how can I just do it within the shortest time? i am a consultant, I did not configured the LAN. the client is not ready to spend much money on man hour or buying any software.
