I have a MDT 2013 server. Everything has been working, except some newer models from Dell are giving me heartburn (specifically the E5470). What happens it is gets to about 91% of applying the image, tries to do the next step and fails (see attached). If I type "net use", the connection to the deployment server has been dropped, but I can re-map it and ping never fails when I have it running in the background. I rebuilt the boot media (built a new MDT server, copied over the WinPE binaries), removed and added the drivers from Intel's site, but nothing will work. It also deletes all the log files from C:\minint\smsosd\osdlogs when it bombs out making troubleshooting difficult, but basically it appears to be dropping the network connection causing it to freak out.
Any ideas? Using the full offline media appears to work mostly fine (I have to add drivers still, but at least the image goes on ) GEN4077-15.zip
