Hi everyone,

        I thought that the following links about DHCP on the Mac
platform might be helpful:

Don't be fooled; it's not just about iMacs. There is one message in
particular which states that Apple correctly implements the
applicable RFC (RFC 2131), but NT servers may not follow it correctly:
