Its work fine but after some days its not work means registration failed. Again when we registered.it's work fine. What can be problem. If you have any idea then please help me i am facing from six month. There could be many reasons why it's not working. But from the details you have mentioned, it seems the problem is due to your DLL getting unregistered somehow. I believe your DLL resides on one of your servers, I would check if there any script or activity happening on your server that is unregistering it periodically and doesn't register it again. I could be wrong here, but do check. Sujit Gupta wrote: What can be problem. If you have any idea then please help me i am facing from six month. Did you check with LinkPoint support? Sohail
