Using Samba 2.2.3a with oplocks completely disabled, our corruption problems
with Microsoft Excel have gone away completely. Thankfully with the acceptable
loads in our environment (vis a vis the capabilities of the server) there has
been no noticeable slowdown in operations even with oplocks disabled.

> Any ideas would be appreciated. Am downloading Samba 2.2.4 right now.

If you are not under intense pressure to fix things, you may want to upgrade to
Samba 2.2.4 while keeping oplocks enabled, and then only disable oplocks if
things still break.

Hopefully the other people on the Samba list will have more tips to share with
you. Good luck with your quest to fix things!
