Vista - Vista Cannot Access Share External Drive On XP Home System

I have XP Home on my desktop and it has an external Western Digital USB
attached drive that I have set up as shared on the network. I also have
allowed updates from netowrk users in the share settings. I can see the drive
from my Vista Home Premium laptop, but when I try to access it I get an
error: "drivename" is not accessible. You may not have permission to use this
network resource. Not enough server storage is available to process this
command.

Now I shared the internal C drive on the desktop with the same share
settings and I can access that drive from Vista with no problem. The only
things I can't access on the C drive are documents and settings, WINNT and
other systems folders, whcih is, I assume, as it should be. Otherwise I can
access all the folders and files on the C drive.

I have Norton Internet Security on the desktop and Norton 360 on the laptop,
but my home network is in the trusted group for both firewalls and, since I
can see the drive and can also access the C drive, it doesn't appear to be a
firewall problem, but some kind of permissions problem, and of course I can't
set permissions on the XP Home system.

Can someone explain to me what is wrong? I have been searching for days on
the web for answers, but as yet have not found a pertinent answer.

I found an article in Computer World which talks about XP and Vista sharing a network. It may provide you with some assistance. Here's the link: Teach XP and Vista to play nice on networks

Thanks Joe. I'll review this article. However I have new information. I added
my daughter's laptop to my home network. Her laptop runs XP Home also. I had
the exact same problem trying to access the external drive from her XP
laptop, but could access the desktop C drive, etc. just as I can from my
Vista laptop. So perhaps this isn't relaled to Vista at all; this makes it
even more confusing. Any further thoughts?

Hi
Vista has enhanced security and some of the shares that are available with
Windows2000 and Windows XP are Not allowed with Vista.
One of them is the Global Share of drive C:\
Successful Sharing involves some general consideration in Network settings,

As well as specific adjustment of each computer according to what it is
allowed to be shared.

Thanks Jack. My problem is sharing an external USB drive attached to an XP
Home system with a Vista system and anoterh XP Home system. The drive is
FAT32; from some of the reading I have done, it appears that maybe this could
be causing permissions problems. Could that be? If I format the drive NTFS
could that help? The article on XP file sharing you referenced seems to
indicate that sharing would work with an NTFS format.

I found reference to the convert.exe utility and am going to look into using
that to reformat the drive.

I used convert.exe to change the format of the external drive from FAT32 to
NTFS. Unfortunately the sharing problem still exits. I am running our of
ideas.
