After upgrading to Mountain Lion, I have experienced some weird problems with network share permissions. This network share is a Windows server which I login to like so: smb://DOMAIN;USERNAME@networkshare.address/folder
What I see

What I cannot do
- Create a new file and save directly to the share.
- Open an existing file and save my changes.
What I can do
- Create new folder
- Delete folders and files
- Rename folders and file
- Move folders and files
- Drag and drop from my desktop to the share drive
Apps that ignore the "problem"
With these programs, I am able to save new file into the share drive and overwrite changes to an existing file.
- Adobe CS6: Photoshop, Illustrator, Dreamweaver, etc
- Microsoft Office: Word, Excel, etc
Apps that display the permissions error message
With most (all?) Mac apps, the permissions error presents itself in some form or fashion.
- TextEdit, Preview
- Pages, Numbers, Keynote
- Coda 2
Coda 2 is unique in that it will let me "Replace" the file, but clicking "Save" will not work.

What else have I tried?
- I have Repaired the Home Directory and Permissions and ACLs
- My IT department has confirmed I have all read/write access to the share drive and has even gone so far as to reapply the permissions to every single folder and file
- I have connected via
cifsand by using the IP address of the server - I have joined the domain via the Users and Groups pref pane (all this does is not ask for your network login anymore when connecting to the share)
- I have confirmed with other coworkers this affects them as well (some with Lion, some with Mountain Lion)
- I have checked the "Ask to keep changes when closing documents" option in the General pref pane
As you can see, this is weird. My IT department suggested I wipe my computer. I don't see how that would have any affect and is really a last resort. I'm hoping someone here can shed light on this before I move forward with that. Wiping the machine and reinstalling the OS doesn't help. Word is that it has something to do with ACLs.
