GUEST credentials issue and can't install ffmpeg on NUC ROCK (ref#6VCOYO)

This is a known issue caused by Microsoft tightening security. The username and password is still guest and guest, to access Roon OS, but now you have to tell Windows that it’s OK to connect to your ROCK system as well. Read this article on how to solve it. Start at step 6 if you have Windows 11 Pro, or step 8 if you have Windows 11 Home.

Hello @eduard.dovbush.

Based on the screenshot you provided, it looks like guest access needs to be enabled in Windows Group Policies. @Geoff_Coupe outlined the steps, but I’m adding them here for quick reference.

For Windows Professional:

6. Disable the SMB client signing requirement:

a. Press Start, type gpedit, and open Edit Group Policy (Local Group Policy Editor).
b. Navigate to:
Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options
c. Double-click Microsoft network client: Digitally sign communications (always)
d. Set it to Disabled, then click OK

7. Enable insecure guest logons:

a. Open the Group Policy Editor again.
b. Navigate to:
Computer Configuration > Administrative Templates > Network > Lanman Workstation
c. Double-click Enable insecure guest logons
d. Set it to Enabled, then click OK

---

For Windows Home:

Since Group Policy Editor is not available by default, you’ll need to use PowerShell:

a. Press Start, type powershell, right-click Windows PowerShell, and choose Run as administrator. Accept the prompt.

b. To disable the SMB signing requirement, run:

Set-SmbClientConfiguration -RequireSecuritySignature $false

c. When prompted, type Y and press Enter.

d. To enable guest fallback, run:

Set-SmbClientConfiguration -EnableInsecureGuestLogons $true

e. Again, type Y and press Enter.

---

After completing the steps, if you still encounter the error when accessing the Nucleus by hostname, try using the IP address instead:

1. Go to Settings → Setup → Find Roon OS
2. Copy the IP address
3. Open File Explorer and enter the path in this format:

\\rock

Let us know if the issue persists after this.
