can you open your own thread and specify your problem there? Talking about your problem here will essentially high jack the OP thread and will lead to confusion.
Do you use pclinuxos2010? what version of windows are you using?
can you try to access those shares using "smb4k"? This program works reliably and should be the default program for accessing samba network shares.
how did you set up your shares? If you used PCC, there is a stage where you are asked something and you are given a choice btw "user" and "share", did you choose "share"?, if yes, redo it agains and choose "user" then go to pcc services area and restart "smb" process, wait for a minute or two and then try to access your linux box from windows
