[c-nsp] IP conflict !!! How to avoid this....

[Church, Chuck]

Different VLAN would fix it, as would taking away the admin rights from a violator's machine, assuming it's Windows NT/2000/XP.  Can't change the address then, short of hacking the admin password.

for each of the "some machines" having static IP, add into the router an
arp entry, linking the IP address to the mac-address.  this way, the
others will be discouraged to even try to change their IP as it will never
work for them.
