"A required device isn't connected or cannot be accessed"
This led us to start looking at the hard drive and the drivers, however, the solution was completely different.
The problem was that the RamDiskTFTPBlockSize we were using on our distribution point was too high, so we had to lower it to the Microsoft default.
To do this, you should follow these steps:
- Go into regedit on your distribution point server
- Browse to HLM\SOFTWARE\Microsoft\SMS\DP
- Find the RamDiskTFTPBlockSize key
- Edit the decimal to "1456"
- Close regedit
