Windows users occasionally encounter various system errors that disrupt their workflow and cause frustration. One such error is System Error Code ERROR_464 — a somewhat uncommon yet impactful error that can affect system stability or software functionality.
If you’ve come across this error and are wondering how to resolve it, you’re in the right place. In this detailed, step-by-step guide, I’ll walk you through effective troubleshooting methods to fix Error Code 464 on your Windows machine.
What is Windows System Error Code ERROR_464?
Before diving into fixes, it’s helpful to understand what ERROR_464 actually means. In Windows, ERROR_464 typically refers to an issue related to the machine or network environment — commonly symbolized as:
“ERROR_464: The specified network name is no longer available.”
This can happen due to network disconnections, corrupted system files, or misconfigured network settings. Sometimes, software attempting to communicate across a network or access certain resources may trigger this.
Common Symptoms of ERROR_464
- Inability to access shared network resources
- Error pop-ups displaying code 464
- Network drives disconnect randomly
- Software freezes or crashes during network activity
- Reduced network performance or unexpected disconnections
Let’s roll up your sleeves and tackle this together. Here’s a comprehensive troubleshooting guide:
Step 1: Restart Your Computer and Network Devices
Sometimes, the simplest fix works wonders.
- Shut down your PC completely.
- Power off your modem and router, wait 1-2 minutes.
- Power on the modem/router first, then your PC.
- Try the operation again that triggered ERROR_464.
This refreshes network connections and clears temporary issues.
Step 2: Check Your Network Connection
- Ensure your PC is properly connected to your local network (Wi-Fi or Ethernet).
- Try pinging your router:
- Open Command Prompt as Administrator.
- Type
ping 192.168.1.1(replace with your router’s IP) and hit Enter. - Look for replies without packet loss.
If ping fails, troubleshoot your network hardware or contact your ISP.
Step 3: Verify Network Drive and Shared Resource Status
If ERROR_464 occurs while accessing a network drive:
- Open File Explorer > This PC.
- Check if the mapped network drives are connected or showing errors.
- To remap a drive: Right-click on the problematic network drive > Disconnect.
- Then, click Map Network Drive and re-enter the network path credentials.
Step 4: Run System File Checker (SFC) Scan
Corrupted system files can cause error interruptions.
- Open Command Prompt as Administrator.
- Type
sfc /scannowand press Enter. - Wait for the scan to complete (may take 10-15 minutes).
- If errors are found, SFC will automatically attempt repairs.
Restart your PC after completion.
Step 5: Reset TCP/IP Stack and Winsock Catalog
Network stack corruption often triggers network-related errors.
-
In Command Prompt (Admin), execute these commands one by one:
bash
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns - Restart your computer.
These commands reset network configurations to their default state.
Step 6: Disable Antivirus or Firewall Temporarily
Sometimes, security software mistakenly blocks network traffic.
- Temporarily disable third-party antivirus or firewall programs.
- Try triggering the network operation again to see if ERROR_464 persists.
Remember to re-enable your security software immediately afterward!
Step 7: Update Network Drivers
Outdated or incompatible drivers can cause errors:
- Press Windows + X and select Device Manager.
- Expand Network adapters.
- Right-click your active network adapter > Update driver.
- Select Search automatically for updated driver software.
- Restart your PC after updating.
Alternatively, visit your network adapter manufacturer’s website to download the latest drivers.
Step 8: Check for Windows Updates
Microsoft regularly patches known issues:
- Go to Settings > Update & Security > Windows Update.
- Click Check for updates.
- Install available updates and restart your PC.
Step 9: Perform a Clean Boot
Software conflicts may cause the error.
- Press Windows + R, type
msconfig, and hit Enter. - On the Services tab, check Hide all Microsoft services.
- Click Disable all.
- Go to the Startup tab, then click Open Task Manager.
- Disable all startup items.
- Close Task Manager, click OK on System Configuration.
- Restart the PC and test if the issue persists.
If fixed, gradually re-enable services to isolate the problematic app.
Step 10: Seek Professional Help If Needed
If the error persists despite your best efforts, it might be time to consult:
- Your IT administrator (if on a workplace network)
- Microsoft Support
- A trusted PC technician
Don’t hesitate — sometimes complicated network issues require an expert’s touch.
