DHCP Preference

[Kirsten]

Is there any way to configure Windows XP clients to use a prefered DHCP
client?
What about using only VALID AND AUTHORIZED (ex: win2003) DHCPs?
I need to prevent a malicious users from a installing a bogus DHCP server.

Thanks

Yes, provided your network meets certain requirements.

Other option is to perform regular portscans for bogus servers.

No. Ian's response, though accurate, does not answer the question. The
answer is that due to the way that DHCP works, it broadcasts a request and
the first server that answers the broadcast gets to assign an address to the
requesting PC. That is designed into the DHCP specification and cannot be
changed.
