Finder problems with samba...

Hi,

I am having some problems with finder when i open the samba server, that is connected wirelessly in my network.

When i open the directory from my desktop, as soon as i open it, it closes finder. Therefore meaning that i cannot access any of the files on samba.

I went to the apple shop yesterday, and spoke to a genius, he suggested i deleted my user preferences for networks, and if that still didnt work to re-install the operating system, ensuring that it cleared the network settings.

I have followed all his advice, and yet it still does not work.

Does anyone have any ideas what the problem could be?

Thanks
