Netbeans deploys code by FTPing it into your cRIO. My guess is that you aren't making the network connection into the robot.

The first thing to check is whether your Netbeans is configured with your team number, since that will determine what IP address it's trying to connect to. Open the Netbeans preferences dialog and select Miscellaneous / FRC configuration to set it.

Next check that your computer is on the correct subnet for the cRIO. The subnet IP addresses are based on your team number.

If you open a command window, you should be able to "ping" or "ftp" straight to the cRIO. This will help diagnosing network problems.
