We have several Dell Optiplex 745's that get the PXE-53 (no boot image found) error. This is befor you get the F8 menu.
Most of our 745's work fine, and we have not seen this on other models.
We have tried updating the Bios to 2.6.1 from 2.3.1 (No broadcom Nic updates we could find)
We have tried different network ports. (including one that we know works on other models)
We made sure there was only one PXE server on the subnet.
We have re-deployed the PXE rep.
We are on LANDesk 8.8 sp1
I have looked at doc-1865 and doc-1143
Any thoughts on what we could try to fix this?
