I first apologize for my english is not so good.

If anyone had this kind of experience pls let me show some direction in which part i need to direct my search for solving the problem.

I do not know is there restriction from application server. if yes pls direct me where i can check and resolve the problem

I have tested from cmd the copy procedure passed successfully.
