Well I’m glad that you can now access your second hard drive
Now for your internet connection; I would use the Device Manager to uninstall the drivers for your network card then remove the network card from the Device Manager altogether, now reboot your system and let windows reinstall your network card. You will probably need to setup TCP/IP for you network card according to your ISP.
As for Norton there is a removal tool available from there website. It is called Rnav2003.exe, run that and then you should be able to reinstall Norton.
As for you burning software Recordnow, I am not familiar with this software but I would suggest that you uninstall this also and then reinstall also check to see if there is a newer version available I think 4.5 is the newest version according to there website.
