How to Fix Windows System Error Code ERROR_465: Step-by-Step

This basic reset can resolve transient network or authentication hiccups.
Step 2: Check Your Network Connection
A stable connection is vital for Windows authentication.
- Click on the Network icon on your taskbar.
- Make sure you’re connected to the correct Wi-Fi or Ethernet network.
- Run the Network Troubleshooter:
- Go to Settings > Network & Internet > Status.
- Click Network troubleshooter and follow the prompts.
Step 3: Verify Your Credentials & Password
Since ERROR_465 often relates to authentication failures:
- Make sure you are using the correct username and password.
- If you’re part of a domain, verify that your domain login details haven’t expired.
- Try logging into your Microsoft account on another device to ensure your credentials work.
If credentials are expired or lost, reset your password.
Step 4: Synchronize Your System Clock
Windows authentication is sensitive to time differences between your PC and the Domain Controller.
- Right-click the Time and Date on the taskbar.
- Select Adjust date/time.
- Toggle on Set time automatically and Set time zone automatically.
- Alternatively, click on Sync now under Synchronize your clock.
This can fix many time-related authentication errors.
Step 5: Clear Cached Credentials
Old or corrupted cached credentials can cause authentication failures.
- Open Control Panel and go to Credential Manager.
- Under Windows Credentials, find any saved credentials related to your domain or network.
- Remove or update them accordingly.
- Restart your PC and attempt to log in again.
Step 6: Check Domain Controller and Network Policies
If you’re in a corporate environment:
- Contact your IT administrator to verify the Domain Controller is reachable and functioning properly.
- Ask them to check for any recent changes in Group Policies or security policies that might affect authentication.
- They might also review event logs on the server for error specifics.
Step 7: Update Your Windows System
Running outdated Windows versions can cause compatibility issues.
- Go to Settings > Update & Security > Windows Update.
- Click Check for updates and install any available updates.
- Restart your PC afterward.
Keeping your system current ensures you have the latest fixes and patches.
Step 8: Use the System File Checker (SFC)
Corrupt system files can trigger error codes.
- Press Win + X, then click Windows Terminal (Admin) or Command Prompt (Admin).
- Type:
sfc /scannowand hit Enter. - Let the scan complete and follow any on-screen instructions.
- Restart your computer.
Step 9: Reset Network Settings
If network configurations are corrupted:
- Open Settings > Network & Internet > Status.
- Scroll down and click Network reset.
- Confirm and let your PC reboot.
This resets all network adapters and should clear network-related authentication errors.
