What initial diagnostic steps should be performed when troubleshooting a `WSAECONNRESET` error?

Initial diagnostic steps include: 1. **Check server logs**: Look for application crashes, error messages, or explicit connection closures on the remote server. 2. **Network connectivity**: Ping and traceroute to the server to check for general reachability and identify any problematic intermediate hops. 3. **Firewall status**: Verify both client-side and server-side firewall rules to ensure they aren't blocking or prematurely closing connections. 4. **Application behavior**: Test with a simple client/server to isolate if the issue is with the application logic or the underlying network. 5. **Reproducibility**: Determine if the error is intermittent or consistently reproducible, and under what conditions.
