SYMPTOMS
You may try to copy files to a Network File System (NFS) share or try to see the file list that is on an NFS share from a UNIX or Linux client. When you do this, you may experience one of the following symptoms, even though the owner of the files is root and is mapped to the NFS share:
 * You receive a &quot;permission denied&quot; error message.
 * You receive a &quot;Stop 1E&quot; system error message, and the system stops.
 * The contents of incorrect files are returned by the NFS server.



CAUSE
This problem occurs because you installed the following hotfix for Microsoft Windows Services for UNIX 2.3:

885930 FIX: Network File System (NFS) client users that do not have the &quot;List Folder / Read Data&quot; permission can still see the file list from an NFS share

Hotfix 885930 causes Server for NFS to close a file handle too soon when it handles a request from a client to list the contents of a directory. On later requests to access the file, such as to read the file or to obtain the attributes of the file, Server for NFS will try to use the file handle that it already closed. This behavior can cause a variety of symptoms. These include the symptoms that are described in the &quot;Symptoms&quot; section.
