Networking problem on 1 of 3 computers

I have 3 computers. Two hard wired into a wireless router and one wireless. One hardwired and the wireless share files perfectly. The other of the hardwired ones, call it the 3rd computer, can see and access all shared files on the other two but the other two cannot access the files on it.
The other two can see the computer NAME of the 3rd in the network directory of each, however.
When I try to access this 3rd computer from either of the other two I get - Error Message: Logon failure: the user has not been granted the requested logon type at this computer."
I can ping the 3rd computer from the other two just fine.
The sharing on the 3rd computer is set properly and have turned off all firewalls.
I've only got TCP/IP installed as protocols on all three.
Any help would be appreciated.
Thanks

 

Check the Local Security Policy and see who has the 'Access this computer from the network' right on the 3rd Computer. If the users trying to access the share do not have this you will receive the error message you are seeing.

 

Can I do all that in XP Home?
Couldn't find Local Services Policy settings to edit.

XP Home only supports authentication by the Simple File Sharing Model.
What Operating System Version are the other two computers using?

If XP Pro, be certain that Simple File Sharing is enabled in Folder Options, View on both.

Then on all three computers:

Start, Run, net user Guest /Active:yes

Try again.

 

All are XP Home.

All have Guest now activated but still same result. (none did before and the two communicated just fine)

I can access all shared files on the other two computers from the 3rd but neither of the other two can get at the 3rd's although they can see it's name in their respective network trees. If I didn't designate any folders or files on the 3rd as "shared" , it would give this result. But that's not the case. It screams of firewall or some other sharing/permissions problem . . .

The only anomoly is that the 3rd unit has the boot drive as E:. For some reason, when I installed XP Home on this system, it assigned the boot hard drive the letter E. That shouldn't have any bearing on this problem, though.

Thanks for the help.

 

E: should have no bearing on this problem. Missing NTRights can, and you have to do some tricks under XP Home. This is not your fault, a lot of XP Home OEM images went out missing the ACE priviliges required. Lets call this the stevewinograd, billcastner,hans-georg michna fix:

1. Download Microsoft NTRIGHTS.EXE

Direct Download link: http://www.dynawell.com/reskit/microsoft/win2000/ntrights.zip

Unzip and move the Microsoft ntrights.exe file to \Windows\System32

You need to do the following on all workstations:

2. The following is done best if you copy/paste into Notepad, and then File, Save as, reset.CMD Double click in Explorer "reset.cmd" :

Restart all computers.

 

Same thing except now it just says "Access Denied "

Strangely, when I go into the Windows Firewall settings page of the 3rd computer, both choices are greyed out but there is a dot in the circle for "not installed ". I cannot change this Firewall page. At the top of this page it says in the bright blue banner that or something similar to "some choices are controlled by Group Policies ". Is there a way to flush this. Something may be getting hung up here.

Thanks.

 

you cant be controled by group polic if you have xp home.

do you have a local security policy enabled, look in admin tools. I am not even sure if home has group policy configuable.
