How to map NAS drive to Hyper-V?

I have a Hyper-V Manager in a workgroup on and a Freecom NAS drive on Both are in a workgroup called JGL.
When creating a new VM I point the .iso location to \\\Software\server2016.iso which it accepts but when I click finish I get the error:
From Windows Explorer I can map to \\\Software and I'm prompted for a username and password and I click "remember" (subsequent connects don't require credentials)
I can't see anywhere in Hyper-V where I can enter credentials.

Windows version?

different user accounts bing used as hyper-v services are not using your user account.. try first logging into the drives as an administrator (cmd prompt run as administrator)
By default the Hyper-V services run as "Local System", this is not the same account that you are using in Explorer.

I would suggest copying the ISO to local storage on the Hyper-V server, or alternatively if you do not want to use local storage for ISOs, if your NAS supports it, create an iSCSI LUN which you then attach to the Hyper-V server and format as normal for ISO storage.

Created an iSCSI LUN on the Synology NAS and mounted that on the Hyper-V server.
