Maven can't connect to remote standalone Selenium server

Question

I am working on creating a test suite for a project at work, where we will be testing our application on several operating systems from a central box (all vms). The box with the tests on is a CentOS server utilizing apache-maven for the tests. I am trying to test against a Windows 10 box running selenium-standalone-server but have had no luck so far. Here is the configuration for each box:

CentOS

Apache Maven
IP address - 192.168.4.62
Subnet mask - 255.255.255.0

Sample Test

package com.netsweeper.browsertests;

import static org.junit.Assert.assertEquals;
import java.net.URL;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.*;
import org.openqa.selenium.safari.*;
import org.openqa.selenium.chrome.*;
import org.openqa.selenium.support.ui.*;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

public class ReadyTest {
    @Test
    public void accessChrome() {
       try {
            WebDriver driver = new RemoteWebDriver(new URL("http://192.168.4.60:4444/wd/hub"), DesiredCapabilities.chrome());
            driver.get("http://google.com");
            assertEquals("The page title should equal Google at the start of the test", "Google", driver.getTitle());
            driver.close();
            driver.quit();
        }
        catch ( java.net.MalformedURLException e) {
            System.out.println("Broken");
        }
    }
}

Test Output

Selenium Standalone Server
- Placed in C:\Users\------\Documents\client_filter\selenium-server-standalone-2.53.0
- Started with java -jar selenium-server-standalone-2.53.0 from said directory
- Correctly starts running
Chrome Driver
- Downloaded and placed in C:\Windows\System32
- Starting it from command line works correctly, so it is in $PATH
- C:\Users\Kendall Roth\Documents\client_filter> chromedriver.exe
IP address - 192.168.4.60
Netmask - 255.255.255.0

However, the error above seems to indicate that the chromedriver is not in the right place to be found, even though it can be found from anywhere (due to being in path). The error was also displayed in the Windows console, and said the same thing.

I have looked around, but can't find anything that deals with a remote install of the Selenium standalone server. This link unfortunately did not work, but was similar to my issue (albeit on a local scale): selenium-2-chrome-driver

As it turns out, it was a rather simple fix. Although C:\Windows\ is not in the system path this was where the chromedriver.exe was supposed to go. Placing it here instead of in C:\Windows\System32\ appears to solve the problem. I'm not sure if this is a remote server only thing or if it extends to local standalone instances as well, but this solution worked for us.

I've found that including the chromedriver.exe in the resources folder within the project to be a workable fail-safe so I don't have to rely on a new user or remote server having the executable in the right location within their file system.
