title: TFS Connection wont connect on lan connection without initiating a ping
body: <p>I am able to connect the tfs in an wink when my pc is connected to the wifi ..
  But when the lan cable is connected &amp; wifi is off it does not connect .. until ..i ping the tfs through my PC .. 2 or 3 drops , it starts pinging and i am able to connect to the tfs .. When i diagnose the connection (inbuit windows function) it shows the error "your computer appears to be correctly configured but the device or resource (dns server) is not responding" .. I did all the steps ( flush , register , relealse , renew ) but the error wont go .. I did this because i thought that may be the problem causing error .. (is it?)</p>
  
  <p>My internet works fine , when tfs is not connected &amp; also when its connected ..</p>
