same ip disrupts my server

[_uNDeRsCoRE]

when someone intentionally or accidentally change the ip address of a pc in a lan to the same ip add as of a server, the server become disrupted (freezes). is there a way to prevent / protect the server from disruption or DOS? tnx :(

from my event viewer:
"The system detected an address conflict for IP address 192.168.0.1 with the system having network hardware address 00:80:C8:E9:A5:45. Network operations on this system may be disrupted as a result."

winnt 4 sp6 (srp)

Yep - do not give any user (except yourself) privs to change tcp settings. Better yet, set a range (x.x.x.50-x.x.x.100) for DHCP for workstations and use the lower numbers for your servers. Only servers really need static ip addresses.

Since we are talking about a private LAN, I don't see how this is a real DOS attack. Is this your home LAN or office?

Which OS is on all the desktops? If it's NT/2000/xp you should be able to control this with permissions. Only give out accounts in the group "user". "Users" cannot edit tcp settings.

If your OS is other, then there may be a third party app that can restrict access to the network settings.
