Samba3.0.23b on Redhat ES4

Thanks for the response. I forgot to add in my original posting that we
did not see this problem with Samba3.0.22 on the same system with the
same smb.conf file.
I notice that in the smb.log file, these errors always occur in pairs -
having exactly the same time, date and content. There is usually a few
minutes between their occurance - sometimes as much as half an hour. I
know this probably isn't much help, but I notice that the errors stop
outside working hours - suggesting (to me) that they are occuring in
response to our users initiating some file/print action on their PC's.
This at least gives me a hint to investigate how to replicate the problem.
Unfortunately I am out of the office for the next week - I will get my
colleauges to gather some more information on the problem and try to
find a way to replicate the errors. Will post again when I have any
Many thanks for your help
