Cannot access ADMIN$ on Windows XP Home from Vista Home Premium

On my home network of 6 computers, 3 Vista Home Premium and 3 Windows XP Home
computers, from my Vista computer I can access ADMIN$ on any other Vista
computer, but I can not access ADMIN$ on any of my Windows XP computers. I
just get "access is denied".

e.g.
GARY is a Windows XP computer
DOG is a Vista Home Premium computer

at a command prompt:
> DIR \\DOG\ADMIN$
(works fine)

> DIR \\GARY\ADMIN$
access is denied.

In an earlier slightly more complicated attempt, I traced a problem down to
a call to WNetAddConnection2, where a valid username and password on the
remote computer was provided. It worked fine Vista to Vista, but always
failed with "access denied" XP to Vista.

I can access any other shared folder I set up on Windows XP:
e.g.
> DIR \\GARY\DAVID
works fine.

On GARY:
>NET SHARE
Share name Resource Remark

-------------------------------------------------------------------------------
C$ C:\ Default share

print$ C:\WINDOWS\System32\spool\drivers
Printer Drivers

ADMIN$ C:\WINDOWS Remote Admin

IPC$ Remote IPC

David C:\Documents and Settings\Gary Deley\My Documents\David
SharedDocs C:\DOCUMENTS AND SETTINGS\ALL USERS\DOCUMENTS
The command completed successfully.

and on GARY, in a failed attempt to fix this, I added to the registry this
key value which previously didn't exist:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters]
"AutoShareWks"=dword:00000001

didn't help.

Soooo, I'm out of ideas. Any ideas? (Is it possible that Windows XP Home
doesn't allow accessing ADMIN$?)

Windows XP Home doesn't have administrative shares like ADMIN$ and C$,
as shown by typing "net share" at a command prompt.

Yet ADMIN$ and IPC$ and C$ show up on all 3 of my Windows XP home computers.
Are they there but just no useable?

ADMIN$ and C$ don't show up on any of my Windows XP Home computers.
They don't appear when I run "net share" on XP Home, and they don't
appear I view an XP Home computer from another computer using "net
view \\xphome". Where do you see them?

The "net share" command shows IPC$ and Print$, which aren't shared
disks or folders.

You might be able to get ADMIN$ and C$ to show up if you start XP Home
in Safe mode, disable simple file sharing, and reboot in normal mode.
This is an unsupported scenario, but it might do what you want.
