Samba's opportunistic locking and MS Office applications don't get along. For a small performance hit you can fix the problem by adding: oplocks = no to the [global] section and fix your problem.

Samba shares a data directory with Word, Excel and Access documents/db's. Also Exact for Dos is running from this share (executable and data). The users experience a long delay every morning opening the first Word document (Word 97, Word 2000). This could take 10 minutes or so. If they close Windows before the document is loaded and open it later on the document is corrupted. If they go for a cup of coffee in the meantime everything is fine. After the first document the rest of them reportedly has no problems (allthough I doubt this). Excel, Access and Explorer have no problems ! This is the global section of the smb.conf: --------- [global] log file = /var/log/samba/%m.log load printers = yes idmap gid = 16777216-33554431 socket options = TCP_NODELAY SO_SNDBUF=8192 SO_RCVBUF=8192 wins server = 192.168.9.5 interfaces = 192.168.9.0/255.255.255.0 username map = /etc/samba/smbusers winbind use default domain = no template shell = /bin/false dns proxy = no cups options = raw netbios name = server02 server string = Samba Server idmap uid = 16777216-33554431 path = /tmp workgroup = WORKGROUP os level = 20 printcap name = /etc/printcap security = user preferred master = no max log size = 50 -------- Samba is running as a workgroup server, no domain integration or fancy stuff. There is still an older Windows 2000 server running as Wins server which is to be replaced by the CentOS server. I find these entries (below) in /var/log/messages which point to locking problems. By Googling I found reports from people who think the stock samba release RedHAt is broken with repect to locking and advice to upgrade to latest version. I would love to here your experiences and thoughts on this cause this gives me the creeps as you can imagine.
