How to use winsat on network share to measure disk-performance under Windows?

I found this post about how to use winsat to measure disk performance on Windows. But if i mount a network share on drive letter x winsat disk -drive x returns Unable to open the drive or device.

I tried to run in regular powershell (since winsat must be run as administrator but administrator shell can't see mounted network shares) using runas /user:myadminname "winsat disk -drive x" but after authenticating i get error that the requested operation requires elevation even though myadminname is a admin user.

I thought about using the idea from here but I don't know the side affects for other users on the system and i don't want to remap a already mounted network drive.

Is there a way to use winsat to measure network mounted disk performance?
