The NET.TCP Port Sharing service is a crucial component of Windows 11 that allows multiple users to securely share TCP ports over the net.tcp protocol. However, users may sometimes encounter issues where this service fails to start, potentially disrupting network communications. This article will guide you through several methods to resolve the “The NetTcpPortSharing service failed to start” error on your Windows 11 system.
Before we dive into the solutions, it’s important to understand that this error can be caused by various factors, including glitches in the service itself, corrupted TCP/IP data, disabled .NET Framework components, recent system changes, or file corruption. Let’s explore the most effective ways to address this issue.
Method 1: Restart the NET.TCP Port Sharing Service
Often, simply restarting the service can resolve startup issues. Here’s how to do it:
Step 1: Press Windows key + R to open the Run dialog, type services.msc, and press Enter.
Step 2: In the Services window, locate “NET.TCP Port Sharing Service”.
Step 3: Right-click on the service and select “Properties”.
Step 4: Set the “Startup type” to “Automatic” if it isn’t already.
Step 5: If the service is running, click “Stop”, wait a few seconds, then click “Start”. If it’s not running, just click “Start”.
Step 6: Click “Apply” and then “OK” to save the changes.
Step 7: Restart your computer to ensure all changes take effect.
Method 2: Re-enable .NET Framework 3.5
The NET.TCP Port Sharing service relies on .NET Framework 3.5. Ensuring this component is properly enabled can often resolve startup issues:
Step 1: Press Windows key + R, type optionalfeatures, and press Enter.
Step 2: In the Windows Features window, find “.NET Framework 3.5 (includes .NET 2.0 and 3.0)” and expand it.
Step 3: Ensure both “Windows Communication Foundation HTTP Activation” and “Windows Communication Foundation Non-HTTP Activation” are checked.
Step 4: Click “OK” and wait for Windows to apply the changes.
Step 5: Restart your computer after the process completes.
Method 3: Reset Winsock
Resetting Winsock can help resolve network-related issues that might be preventing the NET.TCP Port Sharing service from starting:
Step 1: Open Command Prompt as administrator by right-clicking the Start button and selecting “Windows Terminal (Admin)”.
Step 2: Type the following commands, pressing Enter after each:
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
Step 3: Restart your computer after running these commands.
Method 4: Disable IPv6
In some cases, disabling IPv6 can resolve conflicts that prevent the NET.TCP Port Sharing service from starting:
Step 1: Right-click on the Start button and select “Network Connections”.
Step 2: Right-click on your active network adapter and select “Properties”.
Step 3: Uncheck the box next to “Internet Protocol Version 6 (TCP/IPv6)”.
Step 4: Click “OK” to save the changes.
Step 5: Restart your computer and check if the NET.TCP Port Sharing service starts correctly.
Method 5: Perform a System Restore
If the issue started after a recent system change or update, performing a System Restore can help:
Step 1: Type “Create a restore point” in the Windows search bar and open the System Properties window.
Step 2: Click on “System Restore” and then “Next”.
Step 3: Choose a restore point from before the issue started and follow the prompts to complete the restore process.
Step 4: After the restore completes, check if the NET.TCP Port Sharing service starts correctly.
If none of these methods resolve the issue, you may need to consider more advanced solutions like resetting Windows 11, performing an in-place upgrade, or seeking assistance from Microsoft Support. Remember to back up your important data before attempting any major system changes.
There you have it! With these steps, you should be able to get your NET.TCP Port Sharing service up and running again. Keep your system updated and regularly check for any new Windows 11 patches that might address this issue in the future.
