After buying a computer with Windows 7 Pro I stumpled over a very annoying issue when working with Samba shares (Samba v3.5.3) with Windows 7. I opened a Word document, did some changes and when saving it was not longer possible.
Looking into the samba log I found this entries.

Using google I did not found any working solution, I’m not alone with this problem. Apparently, I have to wait until this issue is fixed.
