I had a problem recently with booting to PXE in the following Environment:
DHCP on one VLAN
Altiris PXE server on another
We were trying to get the notebook to boot to PXE and create an image. When booting (F12 - Network boot) to PXE, we were first off all unable to get an IP address from DHCP
This was resolved by adding the option (067) to the DHCP scope options. We were now able to get an IP from DHCP as an IPHelper was also configured on the main switch to allow DHCP traffic over the VLAN's.
However even with this configured we were not able to download the boot file for PXE to function properly, we received some (PXE-e32 * TFTP time-out error) error code.
This was resolved by asking the network guys to add another (2nd) IPHelper onto the main switch, to allow PXE communication over the VLAN's.
Summary of configuration changes:
- Added option 067 to DHCP scope options
- Added IPHelper on main switch to allow for DHCP traffic
- Added IPHelper on main switch to allow for PXE traffic
