Although, the error that you are stating is just an informational message and it should not stop your execution. But, if you are facing problem while execution you would need to check few combinations of IEDriverServer and selenium version to resolve the issue
I would suggest you to use the 32 bit version of IEDriverServer even if your machine has 64 bit OS because I faced slowness issue while using 64 bit IEDriver
Protected mode – Either enabled for all zones or disabled for all zones.
IEDriver.exe – Try using 32 bit
Selenium biniding – 1st try with 3.0. If it doesn’t work, try 2.53.1
