SYMPTOMS
Some Windows applications cannot open a file to write to it after a UNIX application gives it group or world write permissions by means of Server for NFS.



CAUSE
To enforce strict UNIX semantics, Server for NFS enables the write extended attributes permission for only the owner.

The Windows write permission requires write extended attributes to be enabled. A Windows application does not successfully open the file if it requires the general write permission (instead of requiring just the write data permission).

STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.



Alternatively, to work around this issue, follow these steps:
 * 1) Give write extended attributes to the Everyone group in the root directory of the share.
 * 2) Make the entry inheritable by all files and folders.
 * 3) Enable KeepInheritance for the computer.
