Deployment Solution

I have been trying for the past 2 weeks trying to get the PXE server working. 

PXE server is on local subnet (.251.xxx).  DHCP server is on .247.xx.  Have DHCP settings correct for IP of PXE server (DHCP option 66) and BStap.0 file (DHCP option 67).

Checked the services for BootP/PXE/TFTP and they are all running on the PXE server.

Keep getting PXE-E32 Timeout error. 

Ran WireShark network sniffer on PXE server.  Saw that it was receiving BootP Notify and ACK msgs from DHCP server but nothing was being sent out of the PXE server to the client machine.

Tried Windows FTP manually from the client machine to the PXE server and was able to successfully GET the BStrap.0 file from the PXE server using the same path in the DHCP option 67.

What could cause the PXE server to not reply to the DHCP BootP request?  What settings may I have screwed up in setting up the PXE server.

Do you need this DHCP options if the DHCP server is on a different subnet. We dont have them - we just have an IP helper address on the switch.

IP helpers are easier to configure and better long-term.  MS DHCP doesn't support both bootstrap files for BIOS AND UEFI systems, so it becomes a limiting factor.  Network admins balk at setting up IP helpers even though they already did for the DHCP server - they just claim it's a pain, which it's not.  Set them up, remove the DHCP options, and life will be easier.

Verify that your PXE services are running AND that the INI files are in order.  You didn't mention what version of DS you're using.  DS 6.9 works differently from 7.1 which works differently from 7.5, so that's sort of important to troubleshoot if the PXE services really are not working.

GL!

Currently running 7.5

Originally DHCP options NOT set and IP Helper in place -- no good

Added in DHCP options and began seeing the DHCP info on the client machines (all running Legacy not UEFI)

PXE server is getting the BootP but refuses to output anything as the TFTP does not find a BStrap.0 file.

Not sure if it is a bad BStrap file, or if I have some settings in the PXE.Network Boot portion of Altiris wrong.  Appears that all the settings are correct but the client will not receive anything from the server
