Try turning off your oplock i.e. "oplocks = no" to see if the problem
goes away.  MS Office files have a bad history with Samba oplocks, so
that may be the problem you're experiencing.  Do

grep oplock [your log file]

to see if you get any oplock related error messages in your log.  If you
do, then it's an oplock problem.

If, by turning off the oplocks, the problem disappears, you can
selectively turn off oplock on files with the extensions you specify. 
For example,

veto oplock files = /*.doc/*.xls/*.mdb/

will turn off oplocks on Word, Excel and Access files.

Hope this helps.
