PXE-e51. No DHCP or BOOTP offers received. Network boot aborted or terminated.
Cisco switches need to have channelling switched off for the DHCP server side. Channeling is enabled by default. Channelling is a port aggregation mode where you would have multiple ports attached to the same device (a server, another switch, etc.) to spread the load
Try putting the PDHCP server on a separate server than the DHCP server. Doing this fixed an issue with a Cisco VLAN switch where IP helper was enabled to forward client DHCP packets to both the DHCP server and the PDHCP server.

PortFast has been known to have been switched off and this has caused issues on the PXE boot sequence. PXE tends to boot faster and request DHCP faster than the switch can handle.
PortFast has been enabled so that the Switch can start talking to a device without going through the process of waiting for the switch and device to decide what speed they will communicate, by enabling Portfast the switch will open the port and enable packets to flow.
The normal time period for the Switch to open up a port is around 30 seconds, with PortFast enabled the clients can start talking as soon as they are switched on, and in the case of PXE boot services it would not wait for 30 seconds.
Thedocumentationhas a number of helpful hints on how to setup PXE in a network environment.
