On Network GameObject Movment and Rotation Problem.

So I was trying to move and animate my Object Over Network. I tried using this script

 @RPC
 function MovementAround(){
 
             transform.position += transform.forward * WalkSpeed * Time.deltaTime;
             transform.eulerAngles.y = cameraTarget.transform.eulerAngles.y;   
   
             
             
 }             

The GameObject is moving correctly over the network But it's not rotating around with the rotation of the mainCamera following it. cameraTarget is a transform of the MainCamera which have the script "MouseOrbit" for the same GameObject.

I have tried to using this script in a Non-network Game and it works perfectly.

Where is the problem then? Do i have to Observe the rotation or something of the Main Camera using NetworkView or what?
