SMB errors with a C352

[akersrus]

I got this working yesterday, and have been redirecting all of my entries in my address book successfully. Thank everybody for your helpful suggestions, it helped me understand SMB much better.
Thanks again!

I was having the same "Forward TX Error" trying to send files to a mac server. I had set up SMB sharing with SMBUp, and changed the port to 139. The reason turned out to be a permissions problem, the folder was owned by someone else and the login from the machine wasn't allowing files to be created.
