DHCP is keeps assigning my Macbook Pro the same IP address as the server.

I am running a Macbook Pro, version 10.8.5. A few days ago, our firewall took a dirt nap and I had to bypass it while I am waiting on the new firewall. I was able to get the cable modem to dish out the IP addresses and everything else connected and is working fine. Unfortunately, my Macbook Pro isn't connecting due to an IP conflict with the file server. I have rebooted the router, the server and my computer to no avail. I can only connect with a DHCP with a manual address. I have tried to delete the connection and reconnect with a new connection but that still isn't working. Any ideas?

Why isnt the server a reserved IP? Give your mac a static ip for a few days within the ip scope and then set it back to dhcp. Im confused on second thought. Do you have a dhcp and why would the cable modem be doing it? Im sure the modem isnt passing dhcp requests. You would need to enable dhcp relay on it.

The server is a reserved IP....that's the problem. For some reason the network wants to assign my computer the same IP as the server. I can get connected but its a pain because I have multiple buildings on campus  and I have to switch it back every time I connect to the main office.

...oh and BTW I did enable passing on DHCP requests because I am temporarily using the cable modem as the router.

still having the problem.  No changes since I first posted. I still have to change to a manual IP when I am in the office.

You need to set the cable modem's DHCP range to exclude the file server.

For instance, if the file server is 192.168.1.1, set the cable modem DHCP server to serve up addresses only in the range 192.168.1.100 to 192.168.1.200. That should solve the problem.
