Samsung Smart TV SMB Connection Failed — 7 Fixes

Samsung Smart TV SMB Connection Failed — 7 Proven Fixes

Streaming movies, music, and photo libraries from your Windows PC, Mac, or home NAS (Synology, QNAP, TrueNAS) to your Samsung Smart TV using SMB (Server Message Block / Windows File Sharing) is one of the best ways to enjoy home theater entertainment without copying files to physical USB drives.

However, setting up network shares between a PC and a television can frequently result in frustrating network errors:

• "Connection failed / Host unreachable"
• "Invalid username or password" (even with correct credentials)
• "Permission denied / Access restricted"
• The shared folder appears empty or disconnects during playback
• The TV cannot discover your PC name on the local network

These connection failures usually result from Windows network profile restrictions, password-protected sharing policies, local firewall rules, or DNS hostname resolution hiccups. Follow this step-by-step troubleshooting guide to establish a reliable SMB connection on your Samsung TV with AnExplorer.

Fix 1 — Set Windows Network Profile to "Private"

When Windows connects to a Wi-Fi or Ethernet network, it may default to a Public network profile, which automatically blocks all incoming SMB file-sharing requests for security:

How to fix on Windows 10 & 11:

1. On your PC, open Settings → Network & internet.
2. Click on Wi-Fi (or Ethernet depending on your connection).
3. Click on your currently connected network name.
4. Under Network profile type, change the setting from Public to Private (Recommended).
5. Setting your network to Private tells Windows that your home devices are trusted, enabling incoming SMB connections.

Fix 2 — Enable Network Discovery & File Sharing in Windows

If Windows File Sharing services are disabled in the Control Panel, incoming connection requests from your Samsung TV will be rejected:

1. Open Control Panel on your Windows PC.
2. Navigate to Network and Sharing Center → click Change advanced sharing settings on the left.
3. Under the Private network section:
   • Turn ON Network discovery (check "Turn on automatic setup of network connected devices").
   • Turn ON File and printer sharing.
4. Under All Networks:
   • Turn ON Password protected sharing (recommended for secure user authentication).
5. Click Save changes.

Fix 3 — Use Local IP Address Instead of Computer Hostname

Smart TV operating systems running Tizen can struggle with NetBIOS or mDNS hostname resolution (e.g. \\DESKTOP-ABC1234). Connecting directly to your computer's local IP address eliminates DNS lookup failures:

1. Find Your PC's Local IP Address:
   • On Windows: Press Win + R, type cmd, press Enter, then type ipconfig and press Enter. Look for your IPv4 Address (e.g. 192.168.1.150).
2. Enter the IP in AnExplorer on Samsung TV:
   • Open AnExplorer on your Samsung TV.
   • Navigate to the Network card on the Home screen and click + → SMB.
   • In the Server / Host field, enter your IPv4 address (e.g. 192.168.1.150) instead of your computer name.
   • In the Port field, leave the default 445.
   • Enter your credentials and click Connect.

Fix 4 — Verify Windows Account Password vs Windows Hello PIN

A very common cause of "Invalid username or password" errors is attempting to log in using a 4-digit Windows Hello PIN instead of the actual Windows account password:

• SMB authentication requires your full Windows Account Password (or local account password), not your Windows Hello PIN.
• If using a Microsoft Account: Your username is your full Microsoft email address (e.g. [email protected]) and your password is your Microsoft account password.
• Creating a Dedicated Local Sharing Account (Recommended):
  1. Go to Settings → Accounts → Other users → Add account.
  2. Create a local account named TVShare with a simple, secure password.
  3. Grant this user Read permissions on your shared media folder.
  4. Use TVShare and the password in AnExplorer on your Samsung TV.

Fix 5 — Configure Shared Folder & NTFS Permissions Correctly

In Windows, both Sharing Permissions and NTFS Security Permissions must be configured to allow access:

1. Right-click the folder you want to share (e.g. D:\Movies) → select Properties.
2. Switch to the Sharing tab → click Advanced Sharing.
3. Check Share this folder → click Permissions.
4. Ensure your account (or Everyone / Authenticated Users) has Read permission checked → click OK.
5. Switch to the Security tab in the same Properties window.
6. Verify that your user account is listed with Read & execute, List folder contents, and Read permissions.
7. Click Apply and OK.

Fix 6 — Allow SMB File Sharing Through Windows Defender Firewall

If third-party antivirus or Windows Defender Firewall blocks port 445:

1. Open Windows Security → click Firewall & network protection.
2. Click Allow an app through firewall.
3. Click Change settings (admin privileges).
4. Scroll down to File and Printer Sharing and File and Printer Sharing over SMBDirect.
5. Ensure the checkboxes for Private networks are both checked.
6. Click OK and retry connecting from your Samsung TV.

Fix 7 — Synology & QNAP NAS: Enable SMB2/SMB3 & Local Subnet Access

If connecting to a home NAS server:

• On Synology DSM: Go to Control Panel → File Services → SMB → click Advanced Settings → set Minimum SMB protocol to SMB2 and Maximum SMB protocol to SMB3.
• On QNAP QTS: Go to Control Panel → Network & File Services → Win/Mac/NFS/WebDAV → Microsoft Networking → Advanced Options → ensure SMB 2.1 or SMB 3.0 is enabled.
• Verify that your TV’s IP address is not blocked in the NAS Auto Block / Security blacklist.
