VMware question !

Hi,
i have installed VMware on my mac book, and when i try to open VMware file ( its a big win7 file, i have prepared from work )everything works fine but i am keep getting following error..

"Winows cannot access\\vmware-host\shared folders\desktop"

i have tried all the possible option in Vmware sharing settings...
