Hi Mazhar,
I am not exactly sure that I understand what you are saying about what you can see in your system. When you say that the FP-2010 is visible, but the target is not, what target are you expecting to see? The target should be your 2010, and if you can see that and your IP is properly configured, you should be able to communicate with your device. If there is another "target" still visible, but with a red "X" on it, this may be an old or incorrectly configured device, and you can right click on it and select "Delete" to remove it.
If this is not what you are seeing, and you are still unable to communicate with the 2010, please clarify what you are seeing in your remote systems. For more information and troubleshooting advice on how to network your FieldPoint device, see the following link:
