No, the school's DHCP Server issues the ip lease using the DHCP protocol. This is not a "firewall" function -- although depending on where the firewall is, it might have to be configured to permit DHCP packets to pass thru it (moot since other computers are fine). >The number it is receiving start >with 169.xxx and I have been told that this is somewhat of a self >assigned number Correct. If the DHCP Client in Open Transport (your Mac's tcp/ip stack) cannot find a DHCP Server, it creates a "temporary" lease with a 10 minute lifetime. After 5 minutes or so, it will try to contact the DHCP Server again. >I can see others on the network via appleshare Which indicates your hardware is fine. >I tried installing a new system folder, but the >problem remains.

It might help to isolate the problem if you can get your admins to issue you a static IP address and such temporarily, just for testing. If you can talk on the 'net with it, then the problem is specific to DHCP. Some DHCP Servers are set up to only permit "authorized" computers to get ip assignments. This authorization is keyed to either your computer's MAC (ethernet) address, or the DHCP Client ID you set in the TCP/IP control panel. It could be that your school's admins put the wrong MAC in for you... HTH, - Dan. -- MacNetwork is sponsored by <http://lowendmac.com/> and...
