I have an emac running MAC OX Tiger 4.7 set up at a school using DHCP. I can not connect to the internet using DHCP but I can connect to the internet if I enter the network settings manual - borrowing someone's Static IP. The schools network administrator will not allow me to have a manual IP even after I explained it would not work with DHCP. Says that the IP that the DHCP server assigned is a good one and that the computer should work. I've disconnect the computer and reconnected it to a different power and ethernet drop. Hoping to get a different IP - no luck - I tried to force a new IP release - no luck. Someone suggest that I trash the system config and then reboot and reenter the network settings - but if the school's DHCP server has already recorded the Mac address of the computer - won't it give me the same IP number? I don't know what else to do.
