We've got some new Lenovo T500 laptops that won't PXE boot - they give a PXE-E74 error "bad or missing PXE menu...". We're using LANDesk 8.8 SP3 and our PXE Rep is Windows Server 2008 (32-bit).
We've looked at the LANDesk kb doc 2916 which deals with this problem. Our new Lenovo computers are using the version 3.11 BIOS that is mentioned in the kb document. We've tried reducing the number of items in the PXE menu. We have temporarily turned off the Windows firewall on the PXE rep. We've redeployed the PXE Rep. None of this has solved the problem. We are able to PXE boot our older desktop and laptop systems, it seems that only these new Lenovo laptops are affected.
Anybody had success in solving this problem? Any tips on what we might have missed in KB 2916 or any suggestions beyond what is mentioned in the document?
