i posted the same problem 3 weeks ago, I was afraid, I am the only one
this problem.
I am glad, that there others thinking about that problem too, so maybe we
get it fixed.
One try was also to switch off the oplocks, which is not a really good idea,
because several users can work on the same file without noticing it. So they
will override each others changes.
-> oplocks are not file locks. oplocks are about caching files on the client
to improve performance. users wont be able to work on the same file
siultaneously if you disable oplocks.
u should try use sendfile = no. this newsgroup is full with this advice.
In those (for me helpless) last three weeks the users complaining about
problems to save their files grew more and more, they are only w2k -
I have a lot of w98 clients still, never heard a word from them, it is not
only excel causing the trouble, but also word, once I got even with notepad
and a text file with only the word "test" as content.

Meanwhile I did try to undo all the changes I have made before the problem
What I can't easyly undo is the update on the w2k clients, I was pondering
changing the linux kernel-update this weekend ( from 2.4.21 back to 2.4.18 I
had before the problem existed). I don't like that, and I am glad about the
sugesstion checking the switches and NIC's - I never spend a thougth on them
- I think the servers NIC, the switch is a 3COM 4400, but I already had one
damaged of them to, so maybe 3Com isn't that quality assurance I hoped it to
