I was really hoping someone had found a solution to this. My problem is similar.
I have a task sequence that fails while downloading the WIM. It starts downloading, gets to a certain percentage then starts over, it does this a couple times before failing with error 80070002.
ReadDataAndWriteToFile() failed with 0x80072ee2 when downloading 16% of file C:\_SMSTaskSequence\Packages\PRK00025\ENx64W7.wim
ReadDataAndWriteToFile() failed with 0x80072ee2 when downloading 39% of file C:\_SMSTaskSequence\Packages\PRK00025\ENx64W7.wim
Here's the really strange part, If I F8 and ping the server, it replies and the download continues. The ping is losing packets which I suspect is why the download is failing. I plug into the same port with a working laptop and I don't lose packets. I tried updating the drivers in the Boot WIM to the most current version, older versions, same result. I know it's not Network Access Account since the download starts (and finishes as long as I'm pinging). Any ideas?
I've tried newer drivers, older drivers, boundary's look good, This is killing me!
