After I installed Virtual Box guest additions on my debian lenny guest , shared folders just won't work.
No matter what  i did i kept on getting the following error

/sbin/mount.vboxsf: mounting failed with the error: No such device

Finally after spending a couple of days figured  out how to resolve this.

You need to execute the following command as root everytime  you reboot your debian guest os

#modprobe vboxvfs

Another , thing to remember that you cannot mount a drive like C:\ as a shared folder or you will get the following error

/sbin/mount.vboxsf: mounting failed with the error: Protocol error

So make sure that your shared folder is a directory on the host OS.
