Ubuntu 8 (VM) share folder with Vista SP1 (OS)

Hi everybody,

Here's my setup:


The one that works:


OS = Windows XP Pro SP2
VMWare Player 2.03
Ubuntu 8.04 Heron as a Virtual Appliance downloaded
The one that doesn't work


OS = Windows Vista Ultimate SP1
VMWare Workstation 6
Ubuntu 8.04 Heron as a Virtual Appliance downloaded

I want to share files between my OS and my VM. I've got only one hard-disk
and one partition (C. So I want to map a network drive from my VM Ubuntu to
my OS Windows:

In Ubuntu > Places menu > Connect to Server... > Windows share: @IP of my
Windows OS, share folder with Everyone permissions set up on the Windows
shared folder.
Type the correct username and password.
It maps correctly on both OS. Now the difference is:

-> I can create new files and folders with XP as OS
-> I cannot create anything with Vista as OS: it is grayed-out.

There must be a setting on Vista to enable a real share using NTFS
permissions. Where and how?

I also installed ntfs-3g on Ubuntu in just in case it could help, but no
change.

Hope you can help.

Thanks for the suggestions.
