Booting target device to a vDisk was showing the following error after downloading the bootstrap file: “Server [IP Address]:6930: vDisk file access permission denied.”

Solution1: Open services.msc, goto stream service, check the account that stream service is running on. Add that account that runs the “Stream Service” to the security properties of the .vhd and .pvp files. Retry your PVS vm and check.

Solution2: If you have copied the vhd/vhdx file, remove it and copy it again. File might not be copied properly or corrupted.
