Windows BSOD Error 0x00000057 — XNS_INTERNAL_ERROR Fix

What Does This Error Mean?

The 0x00000057 blue screen is called XNS_INTERNAL_ERROR. It points to a serious fault inside the Windows networking stack. This most often appears after a failed Windows update, a corrupted network driver, or a damaged system file. Your computer will restart automatically, but the crash will keep happening until you fix the root cause.

Affected Models

Windows 10
Windows 11
Windows Server 2016
Windows Server 2019

Common Causes

A network adapter driver is corrupted or incompatible with your current version of Windows
A Windows update installed incorrectly and left the networking components in a broken state
Core Windows system files have been corrupted by a sudden shutdown or power loss
Third-party firewall or VPN software is conflicting with the Windows network stack
A failing network interface card (NIC) on your motherboard is generating hardware errors

How to Fix It

Run the System File Checker to repair corrupted Windows files. Open Command Prompt as Administrator and type: sfc /scannow — then press Enter and wait for it to finish.

This scans all protected Windows files and automatically replaces any corrupted ones. It takes about 10 to 20 minutes.
Update or reinstall your network adapter driver. Open Device Manager (right-click Start > Device Manager), expand 'Network Adapters,' right-click your adapter, and choose 'Update Driver.'

If updating does not help, try 'Uninstall Device,' restart, and let Windows reinstall the driver automatically.
Temporarily disable any third-party VPN or firewall software to see if the crashes stop. If they do, that software is the cause — update or uninstall it.

Windows Defender is safe to leave on. Only disable third-party security software for testing purposes.
If the error appeared after a Windows update, roll back that update. Go to Settings > Windows Update > Update History > Uninstall Updates, find the most recent one, and uninstall it.

Microsoft usually releases a fix patch within days of a problematic update. Check for new updates after rolling back.
Run DISM to repair the Windows component store. Open Command Prompt as Administrator and type: DISM /Online /Cleanup-Image /RestoreHealth — then press Enter.

DISM downloads replacement files directly from Microsoft. You need an internet connection for this step.

When to Call a Professional

If running the system file checker and reinstalling network drivers does not stop the crashes, a technician can run deeper hardware diagnostics. A failing onboard network card can be tested and replaced if needed. If the issue started after a Windows update, a technician can also perform a clean Windows installation while preserving your files.

Frequently Asked Questions

Does this error mean my computer is permanently broken?

No. In most cases this error is caused by a bad driver or corrupted system file — both of which are fixable in software. Only if hardware diagnostics show a failing network card would you need a physical repair. Most people fix this error without replacing any hardware.

Why does the blue screen happen so quickly I cannot read it?

Windows is set to restart automatically after a crash by default. To read the full error, go to System Properties > Advanced > Startup and Recovery > Settings, and uncheck 'Automatically restart.' This lets the blue screen stay visible so you can note the error code.

Will my files be deleted if I repair Windows?

Running sfc /scannow and DISM does not delete your personal files. These tools only repair Windows system files. A full Windows reinstall can also keep your files if you choose 'Keep my files' during the process.
