I have a pc which boots a centos pxe boot image over the network. The image is kept in a partition on the DHCP server which assigns a static ip to the pc. Today when I try, the centos image boots over the network and stops halfway saying network unreachable. I am unable to ping the pc from teh dhcp server either.

I do not understand how this could happen. I tried changing the hardware, connections etc. There is no firewall running on the dhcp server either. Would any of you have any idea why this could be?
