Hi all,

My configuration :
Two laptops, one under W7 Pro, the other under W10/20H2 Pro
Both are up to date of latest Windows Update.
Both are connected in same WiFi, both have defined the same Workgroup name.

I have created on both laptops shared folders, and provided, on both, access rights to Everybody
On W10 laptop, I have turned OFF the option : Password protected sharing (in Advanced sharing settings)

From W10 laptop, access to W7's shared files and folders is 100% OK

But from W7, i'm facing a very strange issue :

In Windows explorer, in "Network" section, I can "see" the W10 laptop.
If I click on it, to get the list of shared resources, I get an error message : "You do not have access right..."
But on the other hand, If I enter manually in address bar the full ressource name (\\W10\ResourceName) or even one of its subdirectories (\\W10\ResourceName\xxx\zzz), IT WORKS !! :
- Content of selected directory is displayed in right pane of explorer, and I can browse or access to any file, with access rights (read only or Read write) corresponding to what I have defined in the W10 laptop sharing definition.
- Moreover, in the "network" section, the name of the Resource appears then under the W10 Laptop name, and I can also browse the structure tree.

The ONLY thing I cannot click on in this tree is the W10 laptop name itself, of even the small triangle beside it on left to collapse the tree : this result immedately in the error message " You do not have access right...."

Rather than to enter manually the full ressource name in adress bar, If I have a shortcut targeting it (and after having accessed it once typing its name, I'm able to create such a shortcut), I only have to click on this shortcut to
- get its content in content pane
- make it to appear in tree pane in the Network section

Very strange : This looks like I do not have the credentials to get ressource's list on distant laptop.... but enough credentials to get their content, only provided I know their name !
I tried to deactivate the Firewall (Defender) on W10, but no change. I deactivated it also on W7 (even If i couldn't imagine it may have an impact...)
I even tried to connect both laptops with an alternative WiFi (using my smartphone as hotspot) : no change.

What could be the origin of this issue ?
Since I do not have a third laptop to see what would be its behaviour accessing to the W10 one, I do not even understand clearly if the problem comes from the W10 laptop, or from the W7 ?
I would bet it's more in the W10, but not really sure.

If anyone may have (good or bad, we'll see that later) ideas, I'd be interested in.

Thanks in advance

Just out of curiosity - do you have file and print sharing enabled for the Win10 machine on your connection, and is the connection you're using set to Private / Home / Work versus public?

Yes, of course.
And also Network discovery is activated.

And the network is defined as private / home.

What is very strange in my problem is the fact that sharing works 99% fine : I am able to access contents, I'm able to make them RW or RO, and in the "direction" access to W7 shared resources from W10, it's even 100% OK.
If I didn't activate file sharing, I woudn't be the case.

The ONLY issue is that I'm not able to get resource's list of W10. But able to get their content if I know their name.
And also, but here it's very very minor issue, to collapse resource tree of W10 as seen from W7...

That is definitely an odd occurrence. It would make sense if it either 100% or 0% - but this 99% working is just weird.

Are your security apps on both installs the same / nearly similar?

Same firewall, ie Windows defender (but likely quite different : one is W7, the other W10)
About Antivirus : Free Avast on W7 side, Windows Defender on W10 side.
But I switched recently to Defender. Recently I was with the same Free Avast also on W10... but had exactly the same issue. It is actually to verify if Avast coud be the issue on W10 side that I removed it, and replaced it by Defender.

But I don't want t do the same (ie. remove Avast) on W7 side, for two reasons :
1) because Defender on W7 is not efficient as it is now in W10, and rely only on Defender is to put W7 at risk
2) and anyway, I coudn't understand how Antivirus on W7 side could explain such behaviour. On W10 side, it would already be almost incredible, but even more on W7 side, that is the "client" and not the "server" in the "~ failing" sharing.

According to me, the "root cause" is to be searched in "internal access rights" on W10 computer, that would deny "Everyone" (ie. non identified users) to get list of shared resources.
But this being said... I do not have any idea how to
- check this
- and even more to fix it in case it's actually the problem.

I figured AV should not play a factor - but this is weird.

I'm taking a wild guess here but: have you tried enabling password-protected share access to the Win10 machine, and then attempting to connect from Win 7 using username and password from win 10 machine, and after successful connection, then again disabling password protection for sharing?

Also, is user on Win7 account limited use account?

Compare the permissions list for the two machines. Also, check ownership ( last tab ), you might have to take ownership on the W7 machine to allow access to another machine, its sounds goofy, but thats worked for me in the past, it might not work for you.

You also might want to see if when changing permissions on the W10, the W7 is included in the list.

@johngalt : I just did the test : If password-protected share access is enabled, a login/password is requested (it's the goal of the option....) but after providing correct login, list of shared resources appears.
But after disbling again the option... we go back to the initial situation :cry:

@DTG1 : This confirms me in my asumption it is a matter of access rights defined on the W10 machine.
When password-protected share access is enabled, access rights are those of user I give the credentials (ie. myself, with admin rights)
When it is disabled, I don't know exactly which access rights are applying ? Guest user of W10, EveryOne ?

And which permission lists do you suggest me to verify ? I guess they are the ones of the shared folder, isn't it ?
These permissions are the same on both machines (access rights provided to varous local accounts, plus access rights provided to EveryOne), but moreover, let me remind you that even in the situation I'm not able to get the list of shared folders, I'm able to get their content (provided I know their sharing name to be able to type it in the address bar), and with access rights as defined in these permission : RO or RW.
So, AFAIK, it is not permissions granted to the shared objects themselves that are in cause, but the permission to enumerate list of sharings of the computer. And I do not have any idea on where this permission can (or cannot....) be defined.
I just had a look on gpedit.msc.... but didn't find anything (actually, I thought several times to have foud something interesting, but each time it was false hope...)

But maybe I didn't exactly understood your proposal, so pls don't hesitate to be more specific.
In particular, what do you mean with "to take ownership on the W7 machine"

Anyway, thank you both to have taken time to try to help me.

So, it sounds like you need to check the explicit permissions of the object(s) you're sharing from Win10 to Win7 and make sure they are set correctly. DTG will probably have more to say on this as to which ones and under which user group needs to be looked at - I'm *guessing* that all the perms of 'authenticated users' and the 'Users' groups probably need to be looked at.

But please wait for DTG to get back also - as he will be able to explain more clearly what he asked for in his previous post.

.. you need to check the explicit permissions of the object(s) you're sharing ...

I would say that a little bit differently :
There is no issue on the objects (folders, subfolders and files) themselves, but on the "sharing" itself.

I can see without problem the objects, and I can update them if I give adequate permissions.
What I cannot "see" is the "sharing" itself, not the objects contained in.

It's why I find that very strange....

But I agree : I hope news from DTG !!!

I'm far from being an expert, I can only share what I know, and I could be wrong.

In most cases, subfolders and the lot, inherit all permissions from the parent folder, its the subfolders where you can start to be more specific to block access. The parent folder, if there is one, is where to start if you need to change ownership and permission entries (i.e., Admin/users ). ( for those just reading thru, folder properties > security tab > Advanced)

There is a button to Disable Inheritence so if the parent folder of the shared folder has that disabled, it likely the reason why you cant see there, the subfolder has different permissions. Replace all child objects is need to be checked if you want grant the exact same permissions of the parent folder to all the sub folders and files. Full control access is needed to be able to delete.

This is most common list of security 'groups', this is where ownership is needed to can change access permissions.
access.PNG

The minimum permission is the read and execute to see whats listed in a folder, I think its the same still.

There are only 3 parameters for Sharing permission, Read would needed to see anything inside.


Last thought, sometimes you need to logout and in ( or restart pc ) to apply the changes.

Congratulation, it works !
But maybe it's not directly (or only) due to your suggestion.

I explain : the shared resource is a folder named "Users" directly defined under D:\
(Pls notice that It's not THE"Users" folders of Windows, that is on disk C:, it only has the same name)

Indeed, this folder didn't inherit its access rights from upper level (ie, disk D:\). (The Inheritence button you mention is not actually on the parent but on the child, at least on W10 Pro 20H2)

On the other hand, access rights directly provided to it should have been enough. Actually, all what it could inherit from D: was already defined as "proper access right".

Nevertheless, I wanted to give a chance to your proposal, and I clicked on Enable inheritance.... and it was successful : I became able to "see" the shared resource from the other Pc !

But since I was not comfortable with that (activating the inheritance, I didn't add any access right that was not existing yet without inheritance), I did the inverse test : I deactivated again the inheritance.
And contrary to common sense, to go back to the initial situation.... didn't go back to the initial issue : The shared resource continued to be visible from the other Pc !!!!! (even after rebooting the two Pcs)

My conclusion (even if I'm not sure at all !) : There were "something wrong" in the internal storage of access rights, and modify them in the GUI made Windows to recalculate them, and overwrite current internal storage.... without repeating the "bug".

Whatever, thanks a lot for your answer. Without it, I wouldn't have the idea to "refresh" access rights (since they already seemed to be OK), and my issue wouldn't be fixed !
