Fix: SMB not Working on Windows 11

Server Message Block (SMB) is a critical protocol for file and printer sharing in Windows environments. However, some users have reported challenges with SMB post the Windows 11 update. This guide is designed to help you navigate and resolve these SMB-related issues, ensuring seamless file and printer sharing.

Understanding the Issue

• Protocol Changes: Windows 11 might have introduced changes or updates to the SMB protocol that affect its functionality.
• Network Settings: Incorrect network configurations can hinder SMB operations.
• Firewall Restrictions: Firewalls can sometimes block SMB traffic, leading to issues.

Step-by-Step Solutions

1. Ensure SMB is Enabled

Why it’s Crucial: SMB needs to be active for file and printer sharing.

• Press the ‘Windows’ key on your keyboard.
• Type ‘Windows Features’ and press ‘Enter’.
• In the resulting window, ensure ‘SMB 1.0/CIFS File Sharing Support’ is checked.
