i posted the same problem 3 weeks ago, I was afraid, I am the only one having 
this problem.
I am glad, that there others thinking about that problem too, so maybe we will 
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.

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 - Clients, 
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
