How to disable User folder and Macintosh HD shares?

Hi there,

I recently received my new iMac, and ofcourse wanted to share a public folder with my Windows 7 laptop, and vice versa.

So, in OS X Lion, I checked File Sharing, and the folder "Public", under my User(my name) folder, was succesfully shared.
However, through Windows 7, I could not only see the shared public folder, but also the iMac's full User(my name) folder and Macintosh HD folder, with all their contents.
Obviously, I don't want any other PC to see these two main folders.

I haven't found an option to disable this, or a solution via Google search, hence this thread.

So, what's shared now (accessible via Windows pc):
/Users/(my name)/Public
/Users/(my name)
Volume Macintosh HD


Under the File sharing settings, it only shows the folder "Public map of (my name)", with the correct restrictions.

Why does OS X Lion automatically share everything?

 

No, both computers are signing in to each other as a guest.
I don't have to give a password on any computer in the network.

If I open the Info window of my User(my name) folder, the shared checkbox is unchecked. Same with the Macintosh HD. Which is desired.
But Windows PC can access those main folders anyway.

 

I cannot explain myself better.
I don't have problems with sharing, except that OS X Lion shares everything, instead of the only, manually, shared folder.

 

Now that you've mentioned it, I DO use the same username and password on both my laptop and my iMac. And yes, when tested, I can only see those two big folders when on my laptop, not on any other person's computer in the network.
That's why those big folders aren't checked as "shared".
So it's kinda okay now.

Thank you!
