Synchronizing First Person Controller in a Master Server connection in elevation and azimuth

Hello!. I'm trying to synchronize my first person controller in order to other player can watch what the first one is watching, as an observer. The fact is that I can synchronize the azimuth and elevation angles...Why can I only synchronize in one of both angles?. In the first PC I can watch all around and in the second PC I can only watch and move my head in one type of angle: azimuth or elevation: I can't synchronize both types of angles.

I've put a networkview component on both Main Camera and First Person Controller where the Main Camera is attatched to.

Any idea?

thank you very much.
