Once you've used the Remote Logging Configuration tool to enable logging, you can use the Network Log Viewer tool to view the generated logs. You can launch the Network Log Viewer tool from the Start | All Programs | .NET Compact Framework Power Toys 3.5 menu on your development machine. Navigate to the File | Open menu, and browse for the netcf_Network.log file. Once you've opened it, you should be able to see a screen similar to the following screenshot:

The log viewer shows each network event and packet of data that is sent or received between the mobile device/emulator and the remote service, in sequential order. This is particularly useful when you need to know at which stage exactly an error occurs in a network communication failure.
