Drop a couple of video files into is and then add the folder to Mezzmo and see if your web interface and clients can see the new folder and play the videos. The other question is did your drive lettering change where your video files are stored ?

They were intact because they were stored on a separate NAS and are using the same paths on the new system. I am using the exact same service account that I was using on the previous system, in fact, I also use the service account to log into the box and can access the files just fine from the mapped drives.

To be honest, I'm wondering if it might be more expedient to just nuke the whole database and start over from scratch, including with new folders and playlists. And... If that's the case, what's the purpose of backups...

Even though you kept the account name and PC name the same it is a new build and I believe Windows 10 UAC will still see it as a different user with different permissions. Here's a link for enabling / disabling Windows 10 UAC. I'd try my suggestion first about building a new folder on your new PC and drag a few videos into it. if that works I'd try disabling UAC. This isn't likely a database issue if you are seeing them in the GUI in a folder view (not a playlist view). This sounds more like a permissions issue with the Mezzmo service being able to access the files on the NAS for playback.

I know how to enable/disable UAC. I can play those same files, in the same path, outside of Mezzmo using VLC using the service account that Mezzmo is using.

Also, as another piece of information, Windows Firewall is disabled on this box.

I am pretty sure that the Mezzmo GUI runs under your login account whereas the Mezzmo server, if running as a service, runs as a service/system account, which may have different permissions with regards to accessing the files. I know you said VLC is using the service account but you might still try changing the Mezzmo server from running as a service to running as a console app and see if that resolves the issue. I haven't run VLC that way previously and have always used it with my login account but it's been awhile since I've used it much. Peter will likely respond later today with more ideas.

Yes, it does... And I am logged in using the same service account that I have the service running under... Which is the same service account that I can access the shares. To recap.... The service is running under a service account, I am logged in using said service account, said service account as full control on the shares, said service account is a local admin on the system that I have it running on, the Mezzmo app is running under the same service account.

Because I forgot to put it in my last post... UAC is also disabled for said service account.

This is correct, if the server is running as a service you will need to set the service to run under your user account so that it can access files on remote shares otherwise the server gets an access denied response and lists 0 files.

It's running EXACTLY how it was running on the previous system. The service is running under the account and so is the Mezzmo interface.
