I wasn't even going to touch that issue.

But here is some hard data .. over a 100Mbit/sec switch :

dclarke at aequitas:~$ /opt/csw/sbin/smbd --version

dclarke at aequitas:~$ /opt/csw/bin/findsmb

                                *=DMB
                                +=LMB

So is that okay over a 100Mbit/sec connection ?
