Default Shared folder Asks for password only from one Computer, others connect OK


I had 2 computers on my home network: a laptop with WinXP (SP2) Home
and Desktop1 with WinXP Pro (SP2). I connect to the Internet through a
D-LInk router. Both computers run Comodo Internet Security software. I
successfully set up home network between the two computers (workgroup is
called HOME). Both computers had shared folders set up and I was able to
add a network drive to a file manager.

Now here's the problem: I have bought a new desktop computer Desktop2.
It has WinXP Pro (SP2) with Comodo internet security. Now I did not
need Desktop1 and just disconnected it from the network and did not use
it for some time. I successfully set up networking and folder sharing
between the Laptop and Desktop2. Today I needed a third computer and I
connected the old Desktop1 to the network and booted it up. Then I
wanted to add a shared folder on Desktop2 as a mapped network drive to a
file manager on Destop1 and for some reason, when I type
\\Desktop1\Sharename in the Run command dialog, I get a login dialog
with the Desktop1\GUEST in the user name field (this field is also
greyed out and cannot be changed) and is asking to enter a password (I
get the same prompt to enter GUEST password if I browse for Desktop2 and
try to open it in My Network Places). Naturally, the GUEST account does
not have a password. What's weird though, is that I can connect from
Desktop2 (the new computer) to the old Desktop1 and can see the shared
folder just fine. Only Desktop 1 is asking to enter a password for the
Gest account when connecting to Desktop2. However, Desktop2 connects to
Laptop just fine and Laptop connects to both Desktop1 and Desktop2 just
fine and does not ask for any password.

So the only problem is the connection from Desktop1 to Desktop2. I have
checked network Guest account using *net user guest*, and the account is
active on all computers.

Adding an update...

I have reverted the windows installation on Desktop1 to the backed up
version (the back up was made right after installing the system and with
a minimal configuration) Now both Desktop1 and Desktop2 ask for the
Guest password, but connection to the laptop from both destop1 and
desktiop2 works fine (laptop has Windows home)

I have tried the following with no success:
* "Permitting Network Access Without a Password

To allow users to log onto their computers without a password and then
access the XP Professional machine without a password, you must make a
security policy change:
_x0000_i1035

Go to Control Panel | Performance and Maintenance | Administrative
Tools | Local Security Policy.
Expand Local Policies | Security Options.
Double-click Accounts: Limit local account use of blank passwords to
console login only, which is enabled by default. Disable this option and
click OK.
"
* I have tried unchecking Simple File Sharing in the Folder options/View
tab and setting up two identical accounts with passwords on both
desktops.

Start Control Panel Administrative Tools Local Security Policy

In the window [Local Security Settings], go to:

Security Settings Local Policies Security Options

Select the [Network access: sharing model and security for local
accounts]

Right-click Properties

And choose the value [Classic - local users authenticate themselves]

Note: This trick works only for XP and Vista Pro.
Disable Simple File Sharing (Folder OptionsView tab scroll and clear
checkbox beside "Use simple file sharing (Recommended)"). In
Administrative Tools, Local Security Policy, scroll to find ""Network
access: Sharing and security model for local accounts" and ensure that
it's set for "Classic - local users authenticate themselves".
I also set permissions on the shared folder for EVERYONE to full control

This time the login dialog still appeared, but the user filed was not
grayed out. When I entered the newly created user name and password, the
dialog just came back. So this approach did not solve the problem.

This is probably not the shared folder permissions problem because when
I enter just the computer name in the Run dialog like this \\Desktop1
(or Desktop2) I still get the login dialog. This does not happen when I
run the same command from the laptop with the Home edition of windows
xp. When I run the command \\Desktop1 from the laptop, I get a windows
explorer window where all the shared folder on \\Desktop1 are listed and
then I can open those folders. The problem is two desktop computers
running WinXP Pro require password to log in.

I would appreciate any help with resolving this issue.
