You need to set permissions on the shares AND on the directories so
that the laptop username can see them. Generally this means making the
share and directory readable by the EVERYONE group.

By the way, NEVER share out the root of your C drive, it contains
vital system files and if someone hacks in, your PC can be compromised
totally. Only ever share out secure subfolders.

To give everyone [shudder] access, use Simple File Sharing. See
"How to configure file sharing in Windows XP"
<http://support.microsoft.com/kb/304040/>

However, for anyone with XP Pro (not Home), I strongly recommend
controlled sharing of folders instead of Simple File Sharing. See
"How to disable simplified sharing and set permissions on a shared
folder in Windows XP" <http://support.microsoft.com/kb/307874/>

True, except that Simple File Sharing *isn't* secure.

It's really a bad idea to share the root. Just copy/move whatever files
you want to share to the Shared Documents folder -- that's what it's
for.

Then move it there, which costs no disk space.

THE GOOD
* WPA with a strong password (if it really is strong).
THE BAD:
* MAC filtering is pointless.
* SSID hiding is pointless.
THE UGLY
* You're connected to the Internet
* Your firmware and software undoubtedly have exploitable weaknesses

Why take unnecessary chances in any event?

This doesn't make sense. Firstly you would move the file, not copy it
and secondly the root of your C drive is still on the same 80Gig
drive, so whether you store the file in C:\ or c:\shared_files makes
no difference in terms of space occupied.

BTW a 40GB file is going to be unsharable anyway by any form of
wireless combined with DSL. And what sort of file is 40GB in size,
thats large even for DVD.... ?

*sigh*.

Obscurity is NOT security. Could be worse in hicksville, nothing for
your teen-aged neighbours kids to do of an evening except torch
hayricks and try hacking wireless.
Mac filtering and SSID hiding serve no serious purpose.
WPA is harder to crack but not impossible and anyone with wired access
(eg coming in from the internet) is *inside* your wireless security.

Seems to me that already made up your mind. Thats ok, the purpose of
my post was to point out that you're doing something dumb, not to stop
you doing it. Here's an idea tho - if someone has read access to your
C:\ drive, then with XP Home they can almost certainly read anything
on your entire C drive. For example they could read all your system
config (maybe license keys etc), copy cookie files (eg from your
internet banking) copy emails (eg to your secret lover) copy documents
(eg to your lawyer about your wife) etc etc etc. If you're cool about
that, ok. If you prefer to keep that stuff safe, then share out a
subdir and give no access to Everyone.

Also could you not top post in technical groups, it makes answers very
hard to understand.
