I am getting an error message, Error applying DVD Changes. Failed to add device 'Virtual CD/DVD Disk'. User Account does not have permissions to open attachment., when trying to launch/install a Guest Operating System from an iso image.
HyperV Server: I have installed Hyper-V Server 2016 Tech Preview on a Dell R710 server. In bare metal, no GUI mode.
Windows Server/HyperV Manager: I have installed Windows Server 2016 Tech Preview on a different Dell R710, in full Desktop Experience mode, and have added the Hyper-V Manager as a feature only.
Both machines are in a WORKGROUP only. I have enabled remote administration on HyperV.
I have created a VM in Hyper-V Manager, and am later trying to boot it to an .iso image of Windows 8.1 which is stored in a shared drive on Windows Server 2016 Tech Preview, c:\isos.
I am getting the error message, Error applying DVD Changes. Failed to add device 'Virtual CD/DVD Disk'. User Account does not have permissions to open attachment.
How can I boot this VM from an .iso image ?

I have the same suggestion as Leo - move the ISO file to the Hyper-V machine and attach it to the VM there. When trying to configure this remotely, you run into a number of security issues. From your description it looks like you have not addressed any of them. Making a local copy of the ISO would be the quickest and easiest way to get around all the security issues.

I am not fully clear here.
You say 'shared drive' - Hyper-V cannot mount an ISO during VM boot from a share.
The ISO must somehow be local (local path only) tot he Hyper-V Server during the boot process to install an OS.
The other thing, if you have two server sharing a single disk, you can get into permissions issues if the disk is not a cluster shared volume. One server sets the permissions, then the other, back and forth until you end up with corruption.

Hi Surfdawg,
Have you tried to copy the iso file to Hyper-V server and try again?
Or, you could perform the operation locally.
You could run powershell cmdlets to configure:
