New-iscsiservertarget returns with an UnauthorizedAccessException

Hello all

Can you help me get through an exception that happens on a Server 2016 box?

I'm using the guide from here:
https://model-technology.com/blog/creating-a-ramdisk-in-server-2016-for-io-benchmarking/

New-iscsiservertarget -TargetName “testramdisk”

... generates the output:

New-iscsiservertarget : An unexpected error occurred.
