[Samba] setting file permissions

[Gary MacKay]

I have a very upset client and I can not find an answer. How do I set 
the read-only flag using the Windows Explorer? I right-click, select 
properties, select the read-only check box, click apply and the check 
mark goes away. No errors it just does not work. I browsed the log files 
on the server and did not find anything there either.

RedHat ES 4
Samba 3.0.20a (rpm not hand compiled)
