This is as far as I'm getting and then it fails from there on.
It says something about QAZ00005, but I don't have such folder or file named like that.
In "C:\RemoteInstall\SMSIMAGES\" a folder called "SMSPKG" has appeared with subfolders QAZ00001 and QAZ00002 (QAZ Is my site name) that contains boot.wim files
After some time yet another folder has appeared by the name QAZ00006, but this one contains the entire Windows 7 setup
