5. Reset Your Network Hardware

Resetting your network hardware could be one of the quickest and most effective ways to resolve Error Code 316703. By doing this, you’re essentially refreshing your network connections and clearing any potential issues that might be causing the error. Here’s how you can reset your network hardware:

    • If you see “Windows Resource Protection found corrupt files and successfully repaired them,” this means issues were detected and resolved.
    • If you see “Windows Resource Protection did not find any integrity violations,” your system is free from corruption, and running an SFC isn’t likely to fix Error Code 316703.
