We recently started getting Lenovo M57 (model 6072-C3U) small form factor desktops in and have been struggling in getting them working with LANDesk imaging. I have already tried what was suggested in a document (http://community.landesk.com/support/docs/DOC-2429) but there is no longer an option in Rescue and Recovery to create a rescue boot disk.
To see what drivers are needed I ended up booting one into Windows and looked at Device Manager. I then added the listed driver files to the WinPE image, removed and redeployed the PXE representatives, but had no luck in WinPE connecting to the network. I downloaded the driver file from Lenovo and there are 4 different sets of files for the win32 Pro1000, so I created driver entries in the WinPE image for each of these, again not able to find the network adapter.
At this point I'm stuck, I don't know if there's anything that is being missed or if someone else has already solved this problem and can share the wealth.
