How to Fix NAS Access Not Working on Windows 11: Step-by-Step Solutions

Accessing your Network Attached Storage (NAS) on Windows 11 should be simple, but sometimes it just doesn’t work as expected. This can be frustrating, especially if you rely on your NAS for important files and backups.

There are several reasons why Windows 11 might not connect to your NAS, ranging from network issues to system settings. The good news is, most problems can be fixed with a few straightforward steps.

This guide will walk you through easy and detailed solutions to get your NAS access working again on Windows 11.

Follow each step carefully, starting from the simplest checks to more advanced fixes.

Quick Note Before You Begin

  • Make sure your NAS device is powered on and connected to the same network as your Windows 11 PC.
  • Check your internet and network cables to confirm everything is properly connected.
  • Verify your NAS IP address or network name is correct and reachable.
  • Ensure that your Windows 11 system is updated to the latest version for better compatibility.

Step 1: Check Network Discovery and File Sharing Settings

Windows uses Network Discovery to find devices on your network. If this is turned off, your PC won’t see the NAS.

  1. Click the Start button and open Settings.
  2. Go to Network & Internet > Advanced network settings.
  3. Select Advanced sharing settings.
  4. Under your current network profile (Private or Public), make sure Network discovery is turned On.
  5. Also, turn on File and printer sharing.
  6. Click Save changes.

Why this helps: Network Discovery and File Sharing allow your PC to find and interact with other devices like a NAS on the network.

Step 2: Verify SMB Protocol is Enabled

Most NAS devices use the SMB protocol to share files. Windows 11 may have SMBv1 disabled by default, which can cause connection issues.

  1. Press Windows + S, type Windows Features, and select Turn Windows features on or off.
  2. Scroll down and look for SMB 1.0/CIFS File Sharing Support.
  3. If it’s unchecked, check the box to enable it.
  4. Click OK and restart your computer.

Note: SMB1 is an older protocol and can pose security risks. Only enable it if your NAS requires it and consider updating your NAS firmware to support newer SMB versions.

Step 3: Map NAS as a Network Drive Manually

If automatic discovery doesn’t work, you can try to connect to the NAS by mapping it as a network drive.

  1. Open File Explorer.
  2. Right-click on This PC and select Map network drive.
  3. Choose a drive letter from the dropdown menu.
  4. In the Folder field, enter the NAS address, like \192.168.1.100sharedfolder or \NAS-Namesharedfolder.
  5. Check Reconnect at sign-in if you want the connection to be permanent.
  6. Click Finish.
  7. If prompted, enter the NAS username and password.

Why this helps: Mapping the NAS as a drive lets Windows treat it like a local folder, which often solves access issues.

Step 4: Disable Firewall and Antivirus Temporarily

Sometimes, Windows Firewall or third-party antivirus programs block network connections to devices like your NAS.

  1. Press Windows + S, type Windows Security, and open it.
  2. Go to Firewall & network protection.
  3. Select your current network profile and toggle Microsoft Defender Firewall off temporarily.
  4. Try accessing the NAS again.
  5. If you are using third-party antivirus software, temporarily disable it as well (refer to your antivirus documentation).

Important: Always turn your firewall and antivirus back on after testing to keep your system protected.

Step 5: Restart Network Services

Restarting certain Windows services can help refresh network connections.

  1. Press Windows + R, type services.msc, and press Enter.
  2. Find these services in the list:
    • Function Discovery Provider Host
    • Function Discovery Resource Publication
    • SSDP Discovery
    • UPnP Device Host
  3. Right-click each one and select Restart.
  4. Make sure their startup type is set to Automatic (right-click > Properties > Startup type).
  5. Try accessing your NAS again.

Why this helps: These services manage device discovery and network communication, which are essential for finding your NAS.

Alternative Method: Use IP Address Instead of Network Name

If your Windows 11 PC cannot resolve the NAS device name, try using its IP address directly.

Open File Explorer and enter \[NAS-IP-Address] (for example, \192.168.1.100) in the address bar. This bypasses any DNS or network name resolution issues.

FAQs

Why can’t I see my NAS in the Network section?

Network Discovery might be turned off, or your NAS and PC may be on different network profiles (Public vs Private). Make sure both devices are on the same private network and that Network Discovery is enabled.

What if I get an “Access Denied” error?

This usually means incorrect login credentials. Double-check your NAS username and password. You may also need to configure user permissions on your NAS device.

Do I need to enable SMB1 on Windows 11?

Only if your NAS requires SMB1. SMB1 is outdated and insecure, so it’s better to use SMB2 or SMB3 if your NAS supports them.

How do I find my NAS IP address?

You can usually find it in your router’s connected devices list or on your NAS dashboard/interface.

What if my NAS still doesn’t connect after all steps?

Try restarting both your router and NAS device. Also, check for firmware updates on the NAS.

When Nothing Works

If you have tried all of the steps above and still cannot access your NAS, consider the following final options:

  • Visit your NAS manufacturer’s official support website for specific troubleshooting guides.
  • Reset your NAS to factory settings, but only if you have backed up important data.
  • Contact your NAS support team or a professional technician for help.
  • Check Microsoft’s official Windows 11 support forums for similar issues and solutions.

Conclusion

Fixing NAS access issues on Windows 11 often comes down to ensuring your network settings and protocols are properly configured. Start by enabling Network Discovery and File Sharing, then verify SMB protocol support. Mapping the NAS manually and checking firewall settings are effective next steps.

Remember to use your NAS IP address if the network name doesn’t work and keep your devices updated. If problems persist, don’t hesitate to seek help from official support channels.

With patience and these clear steps, you should be able to restore access to your NAS quickly and securely.
