Hi All,
Here is the answer (at least it was for me and I expect for most of you also).
First, this is a confusion that happens with XP as well as Vista. Second you don't need to be connected to a network to observe this problem. From Windows Explorer on Vista any shared folders will appear in two places: A) Under "Computer" and B) Under "Network" and the subentry for your machine. You should be able to reproduce the kind of problems described in this thread when you try to access the shared folder under "Network". For example, you may be prevented from creating a new file in the shared folder under "Network", but be able to create the file as expected when you do itin the same folder under "Computer".
So what's causing this? The answer isthat there are TWO sets of permissions involved: "NTFS permissions" and "sharing permissions". The folks in this thread are probably getting the "NTFS permissions" set right, but not the "sharing permissions". These are likeinner and outer doors on your home. The inner door (NTFS permissions) may be wide open, but until the outer door (sharing permissions) is also open you can't get in.
To get to both groups of settings for Vista, right click on the folder you are trying unsuccessfully to share and select properties. You should see tabs for both "Sharing" and "Security". Select the "Sharing" tab and press the "Advanced Sharing..." button. Press the "Permissions" button. You should see a list of users hopefully including yourself. What sharing permissions do you have? In my case I had "read" permission but not "change" or "full control". Once I checked those boxes I was able to copy files to the shared folder. Note again that these are the sharing permissions (the "outer door"). I had already given myself full permissions on the "Security" tab (these are the NTFS permissions or the "inner door") and even taken ownership on the "Security" tab, but that wasn't enough.
Couldthe Windows UI be improved to reduce the confusion about these two sets of permissions? Probably, but since the same unclarity was there in XP (and I guess even before) I won't hold my breath

.
Did this fix the problem for any of you?
