>Most NASs are based on Linux and don't support WMI. If the link you show above requires connecting to a "WMI server" on the NAS that's not going to work.
Yes, that is correct.
>NASs typically use Samba to provide SMB/CIFS - compatible file services. So, you'll only be able to use Windows services that are emulated by Samba. My guess is you're going to have to approach it through the properties of network connections/shares rather than properties of the NAS host itself.
Do you know what would be involved in such an approach?
