Well think about it, A differential consists of 3 inputs/outputs. In order for one to move, another has to move as well but not the third. Think about a open diff with one tire in the air. The drive-shaft and the wheel in the air will turn, but the wheel on the ground will not.
So now that we have established that at least 2 out of the 3 inputs/outs have to be moving, lets apply it to your situation (and we are totally ignoring the transfer-case right now).
I am assuming that you have the vehicle on the ground and that you have engaged 4x4 (disconnect engaged). This would mean that 2 of the 3 inputs/outputs are NOT moving. This means that your drive shaft (the third input/output) should in no way rotate. Why? If it is rotating that means that one of the wheels should also be rotating and we know this not to be true as they are on the ground. The only way the drive shaft can rotate then is if the disconnect is not engaging, allowing for the intermediate shaft to turn as if the wheel were indeed off the ground.
Therefore we can conclude that your disconnect is not engaging and needs repair.
Now even if the disconnect was broken, the prop shaft should still not turn because of the resistance from the clutches in the TC being engaged (assuming you are in 4 HI or 4 LO).
Therefore we can also conclude that your TC is either not engaging due to you not engaging it all the way, or the clutches being burnt so they are unable to engage.
