Hello @Jan_De_Prez

Welcome back to the community! I see from your screenshot that you’re hitting an “UnexpectedError” when trying to link your backup to a network share at \\192.168.1.155\roonbu.

This error is a bit of a “catch-all,” but it almost always points to the host machine (the PC or NAS at that IP address) refusing the connection request from Roon.

To help us narrow this down, let’s go through a checklist of the most common “invisible” barriers:

  1. The “Double Lock” (Sharing vs. Security)

If this is a Windows machine, sharing a folder requires two separate steps. If one is missing, Roon will get a “permission denied” error that shows up as “UnexpectedError.”

  • Sharing Tab: Right-click the roonbu folder > Properties > Sharing. Ensure the user has Read/Write permissions.
  • Security Tab: This is the one often missed. Go to the Security tab in that same Properties window. Ensure the same user has Full Control or Modify permissions listed there as well.
  1. Credentials and Passwords

Roon generally requires a username and a password to establish a stable network handshake.

  • Is there a password on the account? Roon often fails to connect to “Guest” or “Public” shares that don’t have a password.
  • We recommend using a local user account on that PC that has a password set.
  1. Firewall & Antivirus

The computer at 192.168.1.155 might be blocking Roon’s “knock” on the door.

  • Try temporarily disabling your Windows Firewall or any Antivirus (like Norton, McAfee, or Bitdefender) and try to add the location again.
  • If it works with the firewall off, you’ll need to create a rule to allow Port 445 (SMB) traffic.
  1. Alternative Path Format

While backslashes (\\) are standard for Windows, Roon’s network engine sometimes responds better to the URI format. Please try entering the path exactly like this: smb://192.168.1.155/roonbu

A quick sanity check: Are you able to access that \\192.168.1.155\roonbu folder from a different laptop or device on your network? If other devices can’t get in, the problem is definitely within the Windows sharing/security settings on that host PC.

Give those a try and let us know which one (if any) gets you past that red error box!

Hi @Jan_De_Prez,

Please accept our apologies that this thread auto-closed without resolution.

Something I don’t see in this thread so far: you mentioned that you’ve set the workgroup correctly, but just for due diligence, have you explicitly allowed insecure guest logins on Windows 11?

The particular steps will depend on whether you have a business or personal Windows 11 instance, but here are some authoritative guides:

  1. Press Win + R, type gpedit.msc, and press Enter.
  2. Navigate to: Computer Configuration > Administrative Templates > Network > Lanman Workstation.
  3. Locate Enable insecure guest logons. Double-click → set to Enabled → OK.
  4. Disable SMB Signing:
  • Navigate to: Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options.
  • Locate Microsoft network client: Digitally sign communications (always).
  • Double-click → set to Disabled → OK.

gpedit.msc >>> can’t find file

i have been searching in windows for what you could mean , the items you do not correspond with what i find. i have made a user in windows ‘roon’ with all security clearences needed (suggestion by copilot): no result. One thing i could find out is that i was working on 2 different networks/gatway. this now correct, but now i get the message that "shared folder: entry is not autorized…” i think i am close now. any suggestions?

The instructions were to Press Win+R which brings up the RUN interface and then type gpedit.msc

OR…

If you type just gpedit in the search area and it will pop up the “Edit Group Policy” in Control Panel which is what you are trying to run. See below..

Pardon me for jumping in here, but if you have set up a local Windows account with a username and password and given that read/write access to the roonbu shared folder, then there should be no need to enable insecure guest logins in your Windows PC…

For example, I created a local Windows account called roon, and added it to my shared folder

Edit: just thought, if by “username” you are trying to use your Microsoft Account username (that looks like an email address), then that won’t work. You have to use the local account form of it - or create a local Windows account for Roon as I did.

You can find out the local account name by opening a Command Prompt window and typing whoami - that will show you your <computername>\<local account name>
