OS X 10.8 Mountain Lion Photoshop CS5 Windows file server save issue

Question

After Lion to Mountain Lion upgrade.
Cannot save or save as to Windows server. Due to "program error." Adobe Photoshop CS5. Can save as fine to local drive. Can also drag and drop in the Finder to this server.
This is Photoshop CS5 12.0.4 (current).
Once the error "could not save filename due to a program error" occurs, the file disappears from the Windows server.
I think it has something to due with the SMB connection.
All other CS5 apps (InDesign, Illustrator, etc.) "save" and "save as" fine. It is also fine performing the same procedure using Preview.

We're in 2015 and this is still an issue with the latest updates from Apple. Any one confirm that the save to network storage problem in Photoshop is gone with the newest version of Photoshop Creative Cloud?
Here's what's happening in our shop as of May, 2015 with both AFP and SMB server connections:
We are using Photoshop CS 5.1, Version 12.1 x64. I believe this is the most up to date version of our CS5.1 software.
We are on OS X Yosemite Version 10.10.3.
When connected to the server via afp (in server log it says "AFP client")
Photoshop gives this error on a save after some changes are made to the file: "Could not save "file name" because write access was not granted." Then, as soon as you hit ok, the file is deleted from the server and is gone within a minute or so. If no change was made to the file, save works fine.
If you use "save as" and keep the same file name, it will usually fail with the same error as above. If you use save as and type in a new file name, all works fine.
If logged in via SMB (in the server log is says "CIFS client")
When you try to save, the error changes to "could not save "file name" because the file was not found." And then as soon as you hit OK on the error, the file is deleted from the server. Using Save As and inputing a different file name presented a new problem, it always says "could not save as "file name" because the file was not found." (in this case SMB seems to be worse than an AFP connection).
This is very frustrating and has been going on in the forums for over 3 years. Shared network environments are commonplace today. It seems to be centered around photoshop and OSX. All other software we use has been working fine with the server / network attached storage.
Thanks for any guidance. Sean
