Problem in Deployment program to Pocket PC

Question

hi, when I deploy my application through VS.NET 2003 using MS Active Sync, I receive the following error: Deploying to Pocket PC Device using TCP Connect Transport Error: Cannot establish a connection. Be sure the device is physically connected to the development computer. Strange that I can see the files on my Pocket PC and can access them. But during deploying why I receive the above error and couldn't deploy? The alternative way I m using is that I manually copy my files to Pocket PC and can run them. But by this way I can't use the debugging facility that is available when I deploy through VS.NET. Please help. Arif.
