Troubleshooting NEBT_TCPIP Error on Windows 11 – Fix Network Connection Issues

Fixing the NEBT_TCPIP Failed Error in Windows 11: A Step-by-Step Guide

The NEBT_TCPIP failed error is a common issue that can pop up when upgrading to or using Windows 11. Identified by Event ID 2505 in the Event Viewer, this error prevents proper network connectivity and can cause frequent disconnections. If you see the message "The server could not bind to the transport \Device\NetBT_Tcpip_{XXX} because another computer on the network has the same name," don’t panic – the fix is usually simple. In this guide, we’ll walk through several methods to troubleshoot and resolve the NEBT_TCPIP failed error on Windows 11.

1. Check Wi-Fi Connectivity

Before diving into complex troubleshooting, first ensure Wi-Fi is enabled and connected. Navigate to Settings > Network & Internet and confirm Wi-Fi is toggled on. Click the Wi-Fi network name, then select "Show available networks" to view all nearby connections. If you expect to see a certain network but don’t, try manually connecting to it.

Why is TPM disabled?

TPM is an international standard for a secure cryptoprocessor that has been around for years. However, it is disabled by default on most motherboards, and that may prevent proper installation of Windows 11. How to use PC Health Check to see if my PC is eligible to install/upgrade Windows 11?

How do I fix network adapter problems after upgrading to Windows 11?

If you recently upgraded the computer, the problem could be a driver or configuration, which you might be able to fix using the network troubleshooter or the network reset feature. To fix network adapter problems after upgrading to Windows 11, use these steps: Open Settings. Click on System. Click the Troubleshoot page on the right side.

Sometimes, Windows 11 drops the connection or fails to auto-connect after waking from sleep. Manually re-selecting the network often resolves basic connectivity issues.

2. Run the Network Troubleshooter

Windows includes a built-in network troubleshooter tool that can automatically detect and fix common problems. Access it by going to Settings > Network & Internet > Status, then under "Change your network settings," select "Network troubleshooter."

The troubleshooter will analyze your network configuration and attempt common fixes like renewing the IP address, flushing the DNS cache, and resetting network components. While not guaranteed to resolve NEBT_TCPIP issues, it’s a good first troubleshooting step.

3. Update Network Drivers

Outdated, buggy, or incompatible network drivers can manifest as the NEBT_TCPIP error. Updating to the latest driver from your device manufacturer ensures maximum compatibility with Windows 11.

You can update drivers manually through Device Manager, or use a free utility like Driver Booster to automatically detect and download the newest drivers. Be sure to restart your PC after installing an updated network driver.

How do I get Windows 11 updates to work?

If you have tried all the above instructions and the device still has problems with Windows Update, you may be able to get updates working by performing a clean installation of Windows 11 as a last resort. Open Microsoft Support website. Under the “Download Windows 11 Disk Image (ISO)” section, select the Windows 11 option.

Does Windows 11 have installation problems?

Since Windows 11 is based on Windows 10, the same installation problems you may see on Windows 10 are likely to appear on Windows 11. This guide focuses on helping you get around common upgrade problems and steps to mitigate specific known issues (if available) during and after the installation.

Can I install Windows 11 on a device that does not meet requirements?

Make sure the device you want to install Windows 11 on meets the minimum system requirements. If your device is currently running Windows 10, we recommend you verify the minimum system requirements using the PC Health Check app. We do not recommend installing Windows 11 on a device that doesn’t meet requirements.

4. Reset the Network Stack

Resetting the network stack restores Windows 11’s network components to their default settings, clearing any problematic custom configurations.

To reset the network stack:

1. Right-click the Windows menu and select "Windows Terminal (Admin)"
2. Type the following commands, pressing Enter after each:

netsh winsock reset netsh int ip reset ipconfig /release ipconfig /renew ipconfig /flushdns

Resetting the network stack combined with a restart will resolve most NEBT_TCPIP errors.

5. Change Your PC Name

As the error message indicates, the NEBT_TCPIP issue surfaces when two PCs on the network share the same name. To eliminate the conflict, change your PC name:

1. Go to Settings > System > About
2. Under "Device specifications," click "Rename this PC"
3. Enter a new unique name and restart your device

With a distinctive PC name, Windows will no longer detect a naming clash on the network.

6. Disable NetBIOS

NetBIOS handles network device naming and sessions on Windows. Disabling it can prevent the name conflict causing NEBT_TCPIP errors:

How do I bypass windows 11 TPM & RAM requirements?

If you just have a regular Windows 11 install disk or ISO, you can bypass the Windows TPM and RAM requirements by making some registry changes during the install. Note that this method only works on a clean install and does not allow you to bypass the requirement for at least a dual-core CPU. 1. Boot off of your Windows 11 install disk.

Should I upgrade from Windows 10 to Windows 11?

If you are upgrading from Windows 10, we recommend that you wait until you are notified through Windows Update that the upgrade is ready for your PC. Windows 11 and check the Windows release information status for known issues that may affect your device. This is the best option for installing Windows 11 on the device you’re currently using.

Does Windows 11 support TPM 2.0?

Microsoft has some strict hardware requirements that your PC must meet to install Windows 11, including TPM 2.0 support. This means that not only older computers, but virtual machines will refuse to upgrade from Windows 10, giving you a message that “this PC doesn’t currently meet Windows 11 system requirements.”

How do I Reset my Network Adapter windows 11?

To reset network adapters on Windows 11 to their default settings, use these steps: Open Settings. Click on Network & internet. Click the Advanced network settings page on the right side.

3. Right-click your network adapter and select Properties
4. Click "Internet Protocol Version 4 (TCP/IPv4)" then Properties
5. Select Advanced > WINS
6. Uncheck "Enable NetBIOS over TCP/IP" and click OK

With NetBIOS disabled over your network adapter, Windows will rely on DNS for name resolution instead. Reboot for the changes to take effect.

Prevent Future NEBT_TCPIP Errors

Once resolved, a few tips will help avoid further NEBT_TCPIP failed errors:

• When connecting to new networks, manually specify the PC name instead of letting Windows automatically generate one

• Periodically update network drivers and Windows to the latest versions

• Don’t enable NetBIOS unless required for legacy devices/software

• Use static IP addresses instead of dynamic ones

  How do I update a Wi-Fi adapter on Windows 10?

  Does Windows 11 support TPM?

  In case Microsoft’s Windows 11 upgrade checker tells you that your PC isn’t supported but it meets all the other requirements then you need to check your BIOS to enable TPM . Almost every modern CPU comes with TPM support. In case you have an Intel CPU then you need to switch to TPM and for AMD you need to check PSP fTPM in the BIOS.

Following the troubleshooting steps above and implementing preventative measures will stop the NEBT_TCPIP failure from recurring and maintain stable Windows 11 network connectivity. Let us know if any issues persist – we’re happy to help get you permanently up and running!
