Dear all,

I have four windows xp pro sp1 pcs. All of them have network shares
that enable others to change.
I have access problem to PC1 and PC2 with the following error:

\\PC1 is not accessible. You might not have permission to use this
network resources. Contact the administrator of this server to find out if
you have access permissions.
Logon failure: the user has not been granted the requested logon
type at this computer.

Information:
1. All of the PCs use the same workgroup name
2. All of the PCs use the same network (192.168.1.X) and subnet
3. All software firewall have been disabled in all pcs
4. All PCs could be shown in Network Neighbour
5. PC1 and PC2 can access freely to PC3 and PC4
6. Error occur when accessing (By UI / UNC) PC3 and PC4, except access their
own, eg. successful when PC1 connecting the \\PC1
7. All of the PCs have the same users (administrator privilege)

The logon failure message indicates that the user account that's
trying to access a shared disk or folder on a different computer
doesn't have the proper access permissions.

On each computer:

1. Click Start | Run, type "secpol.msc" in the box, and click OK.
2. Click Local Policies.
3. Click User Rights Assignment.
4. Click "Access this computer from the network" and make sure that
the Everyone group is included.
5. Click "Deny access to this computer from the network" and make sure
that the Everyone group is NOT included.

Do all PC's have the same password for the same user - meaning does
User1/password1 and User2/password2 exist on ALL computers?

If you created shares with FULL permission, then the only thing that's
stopping you is a properly configured user/password on each machine that
matches the same USER/PASSWORD on the other machines.

Hi,

Or it could be a ForceGuest issue as well.

Note that for Windows XP in a workgroup setting, default all connections
coming from "the network" will be authenticated as the Guest User.

Note that for WinXP Home you cannot disable the ForceGuest behavior
(only in WinXP Pro).

A direct registry edit is possible to change this setting:

HOWTO: Validate User Credentials on Microsoft Operating Systems

http://support.microsoft.com/default...B;EN-US;180548

<quote>
On Windows XP, the ForceGuest registry value is set to 1 by default in
the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

On a Windows XP computer that is a member of a workgroup:

If ForceGuest is enabled (set to 1), SSPI will always try to log on
using the Guest account.

If the Guest account is enabled, an SSPI logon will succeed as Guest
for any user credentials.

If the Guest account is disabled, an SSPI logon will fail even for
valid credentials.

If ForceGuest is disabled (set to 0), SSPI will log on as the specified
user.

Note that "Folder Options/Use simple file sharing" and GPEDIT.MSC and
the "Network access: Sharing and security model for local accounts"
policy setting is just another way of changing the ForceGuest value.
