sharing files over local network some subfolders gives access error

I have two windows 10, one desktop and one laptop.

Both are connecting to the same network.

Both workgroup name are the same WORKGROUP (which is the default)

The desktop (main computer sharing files), has two users

One admin user which have full access

One standard user which is used for network access

The admin user on the desktop shares one of the whole drive, (Hard Drive D) to the standard user who is on the same computer.

On the laptop, there is only one primary user.

This primary user goes to folder explore and enter \\NAME\ on the path

Then an authentication box pops up asking for login username and password

After inputing the standard username and password which exists on the desktop, login is successful and now the primary user on the laptop is able to see the whole drive D which is attached to the desktop.
But somehow, when accessing to some NOT all, only SOME subfolders, I will get an error for accessing denied.
On desktop, using the admin user, I checked if the subfolders' sharing is different from others folders but somehow the settings are the same that I did not change anything. Now this is weird, why on the laptop using the primary user, I can access the drive D and some of its sub directory BUT not all?
If using the admin user on desktop, I tried to share the sub directory to the standard user.

Now the primary user on laptop can finally access that sub directory BUT this sub directory will then also exist into my networks' root path and this really feels weird.

I will see

\\NAME\DRIVE_D\subfolder1

\\NAME\DRIVE_D\subfolder2

\\NAME\DRIVE_D\subfolder3 (lets say this cannot be accessed, after I shared this subfolder directly then....)

\\NAME\subfolder3\ (then under \\NAME\ I would see both DRIVE_D and subfolder3)

This is not making much sense to me.

Can someone please give me some assistance?

Welcome to the forum. You say you shared the whole drive which is by default already shared as d$ which is an administrative share. What folders are you sharing as even on the PC as admin some folders you don't have rights to this is to protect the system. Many folders that are created by a user will be owned by that user

I found out the weird permission why this is happening.

Yes I shared the whole DRIVE_D so all should be the same BUT what I realized is....
the security of subfolder1, inheritance permission is enabled.
there is another subfolder let's call subfolder4, acts the same as subfolder3.
so since I found out about this inheritance permission thing. I took subfolder4 as testing, on desktop the admin user, I enabled the inheritance for subfolder4.
now~ on laptop the primary user can access subfolder4 without getting error anymore!
YEAH!
BUT, I did the same thing with subfolder3, removed subfolder3 from sharing directly.
In this way, I should just see

\\NAME\DRIVE_D\

isn't it?

BUT BUT,
I still see
\\NAME\DRIVE_D\
\\NAME\subfolder3\

this is confusing me again. It's already confusing me that I enabled sharing but for some folders the security does not inherit fine I will do this on my own but why am I still seeing subfolder3 in my root after I cancelled direct sharing which was the reason why it showed up in root folder the first time.
