You have to install a Selenium Server  a Hub  and register your remote WebDriver to it  Then  your client will talk to the Hub which will find a matching WebDriver to execute your test   You can have a look at here for more information

First you need to create HubNode Server  and start the HubNode Server  from command Line prompt using Java  -jar selenium-server-standalone-2 44 0 jar -role hub     Then bind the node Client to this Hub using Hub machines IPAddress or Name with any port number  1024  For Node Machine for example  Java -jar selenium-server-standalone-2 44 0 jar -role webdriver -hub http   HubmachineIPAddress 4444 grid register -port 5566       One more thing is that whenever we use Internet Explore or Google Chrome we need to set  System setProperty  webdriver ie driver  path

This is how I got rid of the error       WebDriverException  Error forwarding the new session cannot find      platform WINDOWS  ensureCleanSession true  browserName internet   explorer  version 11    In your nodeconfig json  the version must be a String  not an integer   So instead of using  version   11 use  version    11   note the double quotes    A full example of a working nodecondig json file for a RemoteWebDriver        capabilities                    platform    WIN8 1          browserName    internet explorer          maxInstances   1         seleniumProtocol    WebDriver         version    11                      platform    WIN7          browserName    chrome          maxInstances   4         seleniumProtocol    WebDriver         version    40                      platform    LINUX          browserName    firefox          maxInstances   4         seleniumProtocol    WebDriver         version    33                configuration            proxy    org openqa grid selenium proxy DefaultRemoteProxy        maxSession   3       port   5555       host   ip       register   true       registerCycle   5000       hubPort   4444       hubHost    your-ip-address

By Default the InternetExplorerDriver listens on port  5555   Change your huburl to match that  you can look on the cmd box window to confirm

This issue came for me due to the fact that    i was running server with selenium-server-standalone-2 32 0 and client registered with selenium-server-standalone-2 37 0    When i made both selenium-server-standalone-2 32 0 and ran then things worked fine
