Have any of the Mac people out there gotten this to work? I had SMB sharing working fine with my Photobridge when my Mac was running Tiger, but upgrading to Leopard seems to have broken SMB; I keep getting a "Port 139 is closed" message when I try to activate a new share on the Photobridge (it's finding the new shares OK, since they show up in the list). I've changed firewall settings and even completel turned off the firewall, and have confirmed that port 139 is open on my Mac by doing a port scan, but I still get "Port 139 closed" messages on the Photrobridge.
The smb.conf file is completely different in Leopard, so Apple has apparently changed the networking code considerably in this new release. I don't know enough about SAMBA to try to figure out what might be different, but I'm hoping that some of the more knowlegable mac users out there might have already figured this one out. I'd hate to have to revert to the previous OS, but I will if I can't get the Photobridge working.
