[Samba] Problem with Samba and NFS on Windows XP

[Andreas Kootz]

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:

So it seams to be a locking-problem. I tried kernel oplocks (=yes and 
=no) and also oplocks. But nothing helped. What is my problem???

Thanks
