new to linux odd networking issue

Okay my windows system some how got corrupted or something basically it would goto the loading screen of windows then turn off back on again, repeat ad nauseum so I ran a bunch of diagnostics and the diagnostics program I could access from the boot menu stated there were no problems whatsoever so a friend who knows a lot about computers told me to get knoppix to move any files I didn't get a chance to back the try and set the computer back to it's factory default so I did and am infact making this message from knoppix there is just one downside. I planned to copy any important files over to my moms shared folder on my network, this is a folder that I have been able to access in the past and now when I goto network through knoppix it mentions her computer in the network but when I click the icon it goes to a completely blank folder, and when I try and copy to her computer it says option not supported by backend. I am probably screwing up do both comps need to be running Knoppix?
