Vista - file sharing

I have a computer running vista premium and a computer running xp home. Vista is nfts file system and xp is fat32 file system. Both are connected to a linksys wired router, both are online. I went to set up files sharing and thought I did. When I check my view network in vista I can see the xp machine and and vista machine. I have no acces to the xp machine. Is this because the xp machine is fat32 file system and vista is nfts. I was just checking some other post on another forum and found that fat32 can read ntfs and vice versa. Please clarify, thanks.

As far as formatting of the drives go, that is negligable. How are your permissions on the xp machine? Can your xp access your vista machine?

OK, for clarification,:

OSs that support NTFS can read both NTFS drives and FAT32 drivers. OSs that do not support NTFS cannot read NTFS drives but can read FAT32 drivers.

The drives never read each other. NTFS does not read FAT32, and vice versa.

Finally, XP can read both NTFS and FAT32 drives, and so can Vista.

So, as Pbb321 said: The type for formatting of the drives plays no factor here.

So what am I missing or not setting up right. This is not really a big deal to share files but would make life a whole lot easier. I just can't figure it out.
