First, I've researched this and found one question that was not answered, and one that was answered not completely. https://serverfault.com/questions/652215/file-sharing-methods (incomplete or vague answer)
Anyway, when I right-click on a folder in 2k8, I hit Properties, then Sharing. Now, I see two options--at the top is "Share..." which allows you to select users and apparently it also sets the Security permissions as well.
However, when I go down to "Advanced Sharing", I see the exact same share name--only none of the permissions I put in the top one are there. (The link above said that "Advanced Sharing" allowed you to add more refined permissions on what was done in the top "Share..." button, but this is not the case.)
Further, when I add a user in the "Advanced Sharing", he does not show up in the top "Share.." section. When I then close out of the top section, that user is REMOVED from the bottom sharing.
So...can anyone explain how these are related and which one takes precedence and more to the point--how does one share a folder on and have any sort of confidence that the users one puts there will actually have access to that share? If one share is a completely different share of the same name then one would think Windows would warn that you're overwriting a share that you'd already carefully set up, but no such warning appears. Thanks,
