unable to reach dhcp server gets 169.254

We have computers connected to a network switch. When you add new computers they get "unable to reach dhcp server gets 169.254". If you connect old working computers to the same network cable that doesn't work with new computers it works. My guess is that either the DHCP server is down or that it has run out of IP addresses to "hand out". Any tips or suggestions where I can continue to look. I don't have access to the DHCP server.

Thank you for your fast answers!
@j33p3r:
I don't know if it is an active switch.
Very probable that there is no port settings in the switch.
The new machines doesn't work when you plug them in. We have tried with several machines and several jacks.
I did ipconfig /renew on several machines and deactivated/activated the network card.
operating system is windows 7/xp

I know that we have not supplied any MAC addresses of the about 20 working computers so this is not the problem.

Just like all you guys said. The DHCP-server had run out of ip-address. Never seen this before. Thanks for your answers.
