Dear all, I have a samba server which gets on directory via NFS from another server. This NFS imported directory is shared from samba with readwrite access. When I open a word-document with Microsoft Winword on Windows NT 4 everything works fine. But when I work with Windows XP it takes a long time to open the file and a long time to save it. On the samba-server I get the following log: [2003/07/23 10:40:44, 0] locking/posix.c:posix_fcntl_lock(657) posix_fcntl_lock: WARNING: lock request at offset 2147483539, length 1 returned [2003/07/23 10:40:44, 0] locking/posix.c:posix_fcntl_lock(658) an No locks available error.

I tried kernel oplocks (=yes and =no) and also oplocks. But nothing helped. What is my problem??? Thanks Andreas
