If you have a problem where Mezzmo server does not list or cannot stream files from network computers or NAS drives, then this can be fixed by managing the way that Mezzmo server runs.
Important: This solution only applies to when you run Mezzmo server as a Windows service. Go to the Media Server Settings dialog to check how you are running Mezzmo server.
By default, when Mezzmo server runs as a Windows service on your computer, it is running user the Windows Local System account and not your Windows user account.
If you have media files on an external NAS drive or another computer, and the NAS drive or other computer has password access, then (Local System) Windows services may not have access these external network resources.
To fix this, you should change your Mezzmo server Windows service to run under your Windows user account instead of the Windows Local System account.
Tip: Some users report that the following Windows setting also helps fix accessing files on NAS drives. In Windows, go to Control Panel\All Control Panel Items\Administrative Tools and run 'Local Security Policy'. Under 'Local Policies', you will find 'Security Options' and under this, you should see a setting called 'Accounts: Limit local account use of blank passwords to console logon only'. Turn this setting off.
