I have an XP machine sharing a folder on my home network. I am accessing this folder from a Win8 computer on the same network. For the most part, this works. But there are a few cases where trying to access a subfolder brings up an error saying that I do not have access to the subfolder. As far as I know, these inaccessible subfolders are identical to the accessible ones except for one thing: they are the TARGET for a junction living in another folder. Would this make a difference? Note that all folders have the same owner on the XP machine, and the only sharing I have done is to right-click on the root d:\sharedFolder, click "Sharing and Security", and check "Share this folder on the network" and "Allow network users to change my files".
Here is an illustration of the setup:
c:\someJunctionA --> d:\sharedFolder\folderA c:\someJunctionB --> d:\sharedFolder\folderB d:\sharedFolder \folderA // inaccessible from my Win8 machine \folderB // accessible from my Win8 machine \folderC // inaccessible from my Win8 machine \folderD // accessible from my Win8 machine
