If you’re encountering Windows ERROR_64, it usually means there’s a problem with your network connection — specifically, “The specified network name is no longer available.” This error can be frustrating, especially if you rely on a stable network for work or leisure. But don’t worry! In this guide, we’ll walk you through detailed, easy-to-follow steps to help you troubleshoot and fix this issue for a smoother online experience.
What is Windows ERROR_64?
Before diving into the fix, it’s helpful to understand what Windows ERROR_64 means. This error typically occurs when:
- A network share or a mapped drive disconnects unexpectedly.
- There is intermittent interruption in your network.
- Network hardware or configuration problems cause the connection to drop.
Common Causes of ERROR_64
- Network timeout due to unstable Wi-Fi or Ethernet connection
- Incorrect or corrupted SMB (Server Message Block) configuration
- Firewall or antivirus blocking network access
- Outdated or faulty network drivers
- Computer or server power-saving settings closing active connections
- Issues with network hardware like routers, switches, or modems
Step-by-Step Guide to Fix Windows ERROR_64
Step 1: Restart Your Network Devices
Before getting technical, start simple:
- Turn off your computer.
- Power down your modem and router.
- Wait 30 seconds to 1 minute.
- Turn on the modem and router first, then your PC once they’re fully powered.
Why it helps: Refreshes your network hardware and clears temporary glitches.
Step 2: Check Your Network Connection Stability
-
Use Command Prompt:
PressWin + R, typecmd, and hit Enter. -
In the Command Prompt, type:
ping google.com -t
Observe if there are dropped packets or long delays.
If you see consistent timeouts or packet loss, this indicates network instability, which might be causing ERROR_64.
Fix:
- Switch from Wi-Fi to Ethernet if possible.
- Move closer to your router.
- Discuss persistent issues with your Internet Service Provider (ISP).
Step 3: Update Network Drivers
Outdated or corrupted drivers often cause network glitches.
- Right-click Start and select Device Manager.
- Expand Network adapters.
- Right-click your network device and choose Update driver.
- Select Search automatically for drivers.
Tip: Visit your PC or network card manufacturer’s website to download the latest stable drivers for your model.
Step 4: Modify SMB Settings
Windows uses SMB for network file sharing, and incorrect settings may trigger ERROR_64.
- Press
Win + R, typeoptionalfeatures.exe, and hit Enter. - In the features list, locate SMB 1.0/CIFS File Sharing Support.
- Toggle it off (uncheck), then click OK.
- Restart your computer.
Why? SMB 1.0 is outdated and can cause issues. Disabling it can improve network reliability.
If you need SMB 1.0 for legacy devices, consider updating those devices or tweaking advanced SMB configurations carefully.
Step 5: Adjust Power Management Settings
Network adapters may power down unexpectedly due to Windows power-saving options.
- Open Device Manager > expand Network adapters.
- Right-click your adapter and select Properties.
- Go to the Power Management tab.
- Uncheck Allow the computer to turn off this device to save power.
- Click OK.
Step 6: Disable Firewall or Antivirus (Temporarily)
Sometimes, security programs can block network communications.
- Temporarily disable Windows Firewall or your third-party antivirus.
- Check if ERROR_64 disappears.
If the error resolves, configure your firewall/antivirus to allow your network apps or services explicitly.
Step 7: Clear DNS Cache and Reset Network Settings
- Open Command Prompt as Administrator.
-
Run the following commands one by one:
ipconfig /flushdns
netsh int ip reset
netsh winsock reset - Restart your PC.
This refreshes your TCP/IP stack and DNS resolver, resolving network misconfigurations.
Step 8: Map Network Drives with IP Instead of Network Name
Sometimes name resolution can fail. Using the IP address can bypass this.
-
Find the IP of your network device or server:
ping
-
In File Explorer, map network drives using:

Extra Tips for Preventing ERROR_64 in Future
- Keep Windows up to date.
- Regularly update drivers.
- Avoid using old SMB versions unless absolutely necessary.
- Maintain healthy network hardware.
- Use wired connections for critical work for more stability.
