Hi Sometimes I'am unable to save files from MS Excel to a Samba server. This behaviour appear randomly on my win2k clients. Looking at samba log files I see: [2002/09/10 10:25:53, 0] smbd/reply.c:reply_lockingX(4387) reply_lockingX: Error : oplock break from client for fnum = 13846 and no oplock granted on this file (directory/file.xls). After inserting option oplocks = false in my smb.conf I have no more error messages in my log file, but the issue still persist. Also tuning oplocks related parameters doesn't make difference. I have find this issue with this samba versions: 2.2.6pre2 (source from samba.org) 2.2.5-1 (rpm from samba.org) 2.2.3a-6.i386 (rpm from redhat 7.3) Thank you very much for your patience. Sorry for my loathsome english.
