2. Start the InterCLASS teacher program.

3. Click Settings> General Settings, then click the "Network Settings" tab on the setting window.

4. Click the "Settings" button under the Basic Settings section.

5. Change the Default port value from 34600 (default) to another value such as 35600.

6. Click "OK" to close the dialog.

7. *IMPORTANT* Click "Apply" (under the same basic setting dialog) to send this setting change to all of the student computers. There is no problem clicking the Apply button a few times.

8. Click OK to close the server settings dialog.

9. Restart all of the student computers from the "Power" button.

10. Restart the InterCLASS teacher program.
