Cannot access folder shares since moving to Windows 11

Upgrading to Windows 11 brings new features and security improvements, but it can also introduce network sharing issues. If you can’t access shared folders after moving to Windows 11, you’re not alone. This problem is usually related to changes in network settings, permissions, or security protocols. Below are common causes and solutions to help you regain access to shared folders.

✅ Check Network Profile

Windows 11 treats networks differently based on their classification. If your network is set to Public, sharing may be disabled. To check:

Go to Settings > Network & Internet > Properties.

Under Network profile, select Private.

This allows your PC to communicate more freely with other devices on the same network.

✅ Enable File and Printer Sharing

File sharing might be turned off by default in Windows 11. To enable it:

Open Control Panel > Network and Sharing Center > Advanced sharing settings.

Turn on File and printer sharing under Private networks.

Also, turn on Network discovery so that other devices can find your PC.

✅ Check Folder Permissions

Even if sharing is enabled, you need proper permissions:

Right-click the shared folder and select Properties.

Go to the Sharing tab and click Advanced Sharing.

Check Share this folder and click Permissions.

Ensure the group Everyone has at least Read permission, or add your user account with appropriate rights.

Also, check the Security tab to confirm NTFS permissions allow access.

✅ Verify SMB Protocols

Windows 11 disables some older protocols like SMBv1 for security reasons. Some devices or networks may still rely on this outdated protocol:

Open Control Panel > Programs > Turn Windows features on or off.

Scroll down and enable SMB 1.0/CIFS File Sharing Support if necessary.

However, enabling SMBv1 should be a last resort since it poses security risks.

For modern setups, ensure SMBv2 or SMBv3 is enabled and working.

✅ Check Credentials and Password Protected Sharing

If password-protected sharing is enabled, you’ll need the correct username and password to access shared folders:

Go to Advanced sharing settings.

Under All Networks, you can disable Password protected sharing temporarily to test access.

Alternatively, ensure you’re entering the correct credentials when prompted.

✅ Firewall and Antivirus Settings

Sometimes, firewalls or antivirus software block file sharing:

Check that File and Printer Sharing is allowed through the Windows Defender firewall.

If using third-party security software, ensure it’s not blocking local network traffic.

✅ Mapping the Shared Folder

If browsing doesn’t work, try mapping the folder manually:

Open File Explorer.

Click This PC > Map network drive.

Enter the folder path and check Reconnect at sign-in.

Final Thoughts

Accessing shared folders on Windows 11 may require a few adjustments after upgrading. By checking network profiles, enabling sharing options, verifying permissions, and ensuring correct protocols are active, you can usually restore access quickly. Always be cautious when enabling older protocols like SMBv1 and adjust security settings responsibly.
