Error when passing IE version to Selenium Grid - selenium

Question

I'm trying to pass a simple test to my Selenium grid, while specifying which version of IE to run the test on.
I've started my node like this:
java -jar selenium-server-standalone-2.52.0.jar -role webdriver -hub http://192.168.1.201:4444/grid/register -browserName="internet explorer",version=10.0,platform=WINDOWS -Dwebdriver.ie.driver=C:\IEDriverServer.exe
I see the node register to the hub with version 10, looks OK.
Then I start my test like this:
IWebDriver driver;
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities = DesiredCapabilities.InternetExplorer();
capabilities.SetCapability(CapabilityType.BrowserName, "internet explorer");
capabilities.SetCapability(CapabilityType.Platform, new Platform(PlatformType.Windows));
capabilities.SetCapability(CapabilityType.Version, "10.0");
driver = new RemoteWebDriver(new Uri("http://192.168.1.201:4444/wd/hub"), capabilities);
But I get the error:
Result Message:
System.InvalidOperationException : Error forwarding the new session
cannot find : Capabilities [{platform=WINDOWS, browserName=internet explorer, version=10.0}]
TearDown : System.NullReferenceException : Object reference not set to an instance of an object.
The test can run when I don't specify the IE version, so the issue must be there - what is failing here?

Answer 1

I think browser version should be "10" without ".0":
capabilities.SetCapability(CapabilityType.Version, "10");
You also don't need to initialize DesiredCapabilities twice, and then change settings once again. You can just set them to correct values in constructor, so 5 lines collapse into 1:
DesiredCapabilities capabilities = new DesiredCapabilities( "internet explorer", "10", new Platform(PlatformType.Windows) );

Answer 2

I figured it out.
When registering a node as a browser version, you have to surround the browser parameters set with quotation marks. My new node startup command is:
java -Dwebdriver.ie.driver=C:\IEDriverServer.exe -Dwebdriver.chrome.driver=C:\chromedriver.exe -jar selenium-server-standalone-2.52.0.jar -port 5555 -role node -hub http://192.168.1.201:4444/grid/register -browser "browserName=firefox, maxInstances=10, platform=ANY, seleniumProtocol=WebDriver" -browser "browserName=internet explorer, version=10, platform=WINDOWS, maxInstances=10" -browser "browserName=chrome,version=ANY,maxInstances=10,platform=WINDOWS"
