Thank you Does Roon Rock work on SMB1??!!?? That’s super dangerous!

No - it doesn’t. It uses SMBv2. The issue is caused by Microsoft being ultra cautious. Valid for business networks, but overkill in a home network.

I uploaded the codecs to the CODECS directory (the ffmpeg file), but after restarting the server, I’m still getting a message saying the codecs are missing.

Did you copy the archive or extract and copy a single file: ffmpeg?

I repeated the procedure and it works. On Windows Pro 25H2, there are no “Lanman” or “Insecure Guest Logon” options in Group Policy Editor; the easiest way is to use PowerShell and enter: Set-SmbClientConfiguration -EnableInsecureGuestLogons $true Additionally, regarding SMB1—the nmap scan result…
