Host: Windows XP Pro SP3. Client Windows 7.
On the host I have a directory that's shared. While it's technically writable I never do so. Under it are some folders into which volumes have been mounted. (This exposes all the volumes while only using up one drive letter.)
The original stuff worked after some struggle but now I'm trying to add another couple of folders. They show up fine on the client but the client sees them as read-only. Since the whole purpose of this exercise is backup that's utterly useless.
I've tried recreating the share, no change.
This isn't a reporting illusion, the folders really are read-only. Any attempt to create a file in them from the Windows 7 machine fails.
It's just workgroup sharing. I'm the only user, this is just drive space for backups, nothing fancy.
I just tried writing to the top level directory, it worked. The subdirectories have the "Inherit from parent the permission entries that apply to child objects" box checked. Examining the effective rights for one of the offending subdirectories shows EVERY user on the box can write to it.
I think it must somehow be connected to the fact that these subdirectories have volumes mounted in them.
Stranger and stranger: I created a share on one of the offending directories and it also shows up as read-only on the client!
