- Are you on the same network or VPN as the resource?
Understanding where and when the error occurs is crucial for targeted troubleshooting.

Win + R, typecmd, and press Enter. -
Type
ping [network resource IP or hostname]. For example,ping 192.168.1.10
- If the ping fails, there is a connection issue between your PC and the resource.

Turn off your router, modem, and any switches. Wait 30 seconds and turn them back on.
Step 3: Make Sure the Network Resource is Available

Step 5: Check Permissions for Network Access
- Ensure your user account has correct permissions to access the network resource.
- On the host computer or server, confirm the shared folder/printer is configured to allow access for your account or group.
Step 6: Remove & Re-Add Network Drives and Printers
If network drives or printers are mapped incorrectly, they may throw ERROR_57.
