How to setup SMB Network drive connection on HyperV Server?

I'm used to work with VMWare ESX before, I have some basic knowledge of HyperV.

Except this one:

I want to mount my network location \\NAS\OperatingSystems\ to my HyperV server, so I can access my iso files fast and quickly when installing new machine on my HyperV test and education lab.

I known you can do this via gpo network drive connections but than a user needs to login.  When you boot up HyperV there is no user logged in so?

Thanks!
