Hello, We've been running Samba 2.x since it's out, and are happy with it! We have several smb-servers and several workgroups. In 1 of the workgroups, authentication is done on Samba server A (Solaris for Intel), while most (not all) of the client mounts happen from Samba server B (Debian Linux). On server B, I see a lot of write failures in the logs. On server A, I rarely see them. I read the mail archives about the problem, and saw the suggested solution (reverse DNS settings). But our clients always have had reverse DNS records, and I have the problem on only one server. Another strange thing is that there is always exactly 300 seconds (6 minutes) between 2 "write failure" logs. Server A is a secondary DNS server, server B is not a DNS server. Could that be the "problem"? I have other (Linux) servers with Samba which are not DNS servers and do not have the errors... What can I do to further debug? BTW, I use Samba 2.0.7 on all machines.
