How to make JFileChooser Default to Computer View instead of My Documents

Question

In the Windows Look and Feel for JFileChooser, the left hand side of the JFileChooser dialog shows five buttons: Recent Items, Desktop, My Documents, Computer, and Network. These each represent Views of the file system as Windows Explorer would show them. It appears that JFileChooser defaults to the My Documents View unless the setSelectedFile() or setCurrentDirectory() methods are called.

I am attempting to make it easy for the user to select one of a number of mapped network drives, which should appear in the "Computer" View. Is there a way to set the JFileChooser to open the "Computer" view by default?

I have tried a couple methods to force it, the most recent being to find the root directory and set it as the currentDirectory, but this shows the contents of that root node. The most recent code is included below.

private File originalServerRoot;
private class SelectOriginalUnitServerDriveListener implements ActionListener
    {
        @Override
        public void actionPerformed(ActionEvent e)
        {
            JFileChooser origDriveChooser = new JFileChooser();
            origDriveChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
            File startFile = new File(System.getProperty("user.dir")); //Get the current directory

            // Find System Root
            while (!FileSystemView.getFileSystemView().isFileSystemRoot(startFile))
            {
                startFile = startFile.getParentFile();
            }

            origDriveChooser.setCurrentDirectory(startFile);
            origDriveChooser.setDialogTitle("Select the Mapped Network Drive");
            int origDriveChooserRetVal = origDriveChooser.showDialog(contentPane,"Open");
            if (origDriveChooserRetVal == JFileChooser.APPROVE_OPTION)
            {
                originalUnitServerRoot = origDriveChooser.getSelectedFile();

            }
        }
    }

Is there a method that allows me to select the "Computer" view by default (or the Network, or any other view), or any way to trick the JFileChooser?

EDIT
Thanks for the quick and thorough answers. I combined Hovercraft Full Of Eels' and Guillaume Polet's answers to try and make the code work on any drive letter. The resulting code is as follows. Once again, thanks.

private File originalServerRoot;
private class SelectOriginalUnitServerDriveListener implements ActionListener
    {
        @Override
        public void actionPerformed(ActionEvent e)
        {
            JFileChooser origDriveChooser = new JFileChooser();
            origDriveChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
            File startFile = new File(System.getProperty("user.dir")); //Get the current directory

            // Find System Root
            while (!FileSystemView.getFileSystemView().isFileSystemRoot(startFile))
            {
                startFile = startFile.getParentFile();
            }
            //Changed the next line
            origDriveChooser.setCurrentDirectory(origDriveChooser.getFileSystemView().getParentDirectory(rootFile));
            origDriveChooser.setDialogTitle("Select the Mapped Network Drive");
            int origDriveChooserRetVal = origDriveChooser.showDialog(contentPane,"Open");
            if (origDriveChooserRetVal == JFileChooser.APPROVE_OPTION)
            {
                originalUnitServerRoot = origDriveChooser.getSelectedFile();

            }
        }
    }

Here is a working example. It makes the assumption that C:\ is a valid path. It uses the FileSystemView.getParentDir(File)

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;

import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                new Test().initUI();
            }
        });
    }

    protected void initUI() {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel panel = new JPanel();
        final JButton button = new JButton("Select files...");
        button.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                final JFileChooser chooser = new JFileChooser();
                chooser.setCurrentDirectory(
                                 chooser.getFileSystemView().getParentDirectory(
                                     new File("C:\\")));  
                            chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
                chooser.showDialog(button, "Select file");
            }
        });
        panel.add(button);
        frame.add(panel);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}
