Sometime I have problem with packages not downloading and in smsts.log I get this error.
Download() failed, 80072ee2.
The only way I have found to fix this when it happen are to use the variables
SMSTSDownloadRetryCount = 5
SMSTSDownloadRetryDelay = 15
Set the at the top in your Task Sequence as shown here, and the problem I had diapered.
I would like to know the reason and what the problem is, so let me know if you got an idea
