What is Windows Error Code ERROR_46?
ERROR_46 is a somewhat generic Windows system error indicating “The network bios session limit was exceeded” or sometimes related to problems accessing certain system files or resources. It often appears when trying to access shared network resources, or during specific software operations.
Understanding the root cause is crucial to fixing it because the error can be triggered by:
- Network-related limitations or misconfigurations
- Corrupted or missing system files
- Security software blocking access
- Outdated or incompatible drivers
Step 1: Reboot Your Computer and Network Devices
Sometimes, the simplest fix is the best place to start.
- Restart your PC. This can clear temporary glitches and system locks causing ERROR_46.
- Restart your router and modem if the error appears during network access. Unplug them for 30 seconds, then plug back in.
This quick step resolves many temporary network and system-related errors.
Step 2: Run Windows Network Troubleshooter
If the error relates to network sharing or accessing network resources:
- Click Start → type “Settings” → hit Enter.
- Navigate to Network & Internet → Status → click Network troubleshooter.
- Follow the on-screen prompts to detect and fix network problems automatically.
Windows built-in tools can spot configuration issues that cause ERROR_46.
Step 3: Check and Adjust Network Session Limits
Since ERROR_46 can mean the network session limit is exceeded, adjusting these settings may help:
- Press Windows + R, type regedit, and press Enter to open the Registry Editor.
-
Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
- If not present, create a new DWORD value named MaxMpxCt.
- Set its value to a higher number (e.g., 50 or 100) to increase session limits.
⚠️ Backup your registry before making changes to avoid system problems.
Step 4: Run System File Checker (SFC) and DISM
Corrupted system files are a common cause of this error.
- Open Command Prompt as Administrator.
-
Type:
sfc /scannow
- Wait for the scan to complete and follow any prompts.
-
If issues persist, run:
DISM /Online /Cleanup-Image /RestoreHealth
- Restart your PC after completing both scans.
Step 5: Update Network Drivers
Outdated or faulty drivers can lead to ERROR_46.
- Press Windows + X, select Device Manager.
- Expand Network adapters.
- Right-click your network device → Update driver → Search automatically for updated driver software.
- Follow prompts and restart if needed.
Alternatively, visit your PC or network card manufacturer’s website for the latest drivers.
Step 6: Temporarily Disable Firewall or Security Software
Sometimes, security software or firewall settings accidentally block network sessions or file access:
- Temporarily disable your antivirus and firewall.
- Check if ERROR_46 still occurs.
- If the issue resolves, add exceptions for trusted programs or network locations in your security software’s settings.
⚠️ Remember to re-enable security software afterward to keep your system protected.
Step 7: Verify Network Sharing and Permissions
If ERROR_46 arises while accessing shared resources, verify sharing settings:
- Right-click the shared folder or drive → Properties → Sharing tab.
- Click Advanced Sharing → ensure Share this folder is checked.
- Click Permissions, ensure your user account or group has adequate permissions.
- Click Security tab and confirm permissions for network users.
Step 8: Reset TCP/IP and Network Configurations
Resetting your network stack can clear corrupted network settings:
- Open Command Prompt as Administrator.
-
Run these commands one by one:
netsh int ip reset
netsh winsock reset
ipconfig /flushdns - Restart your PC.
Step 9: Perform a Clean Boot to Isolate Software Conflicts
If the error started recently, third-party software may be the culprit.
- Press Windows + R, type msconfig, and press Enter.
- Under the Services tab, check Hide all Microsoft services and click Disable all.
- Go to Startup tab → open Task Manager → disable all startup items.
- Restart your PC and check for ERROR_46.
- If resolved, re-enable services one-by-one to find the conflicting app.
Step 10: Seek Professional Help or Reinstall Windows
If none of the above steps fix ERROR_46:
- Consider contacting Microsoft Support or a trusted technician.
- As a last resort, backing up your files and performing a clean Windows installation can often eliminate persistent errors.
