It sounds like the server is not responding for some reason. We'll
probably need to see a network capture to understand what's going on:
http://wiki.samba.org/index.php/LinuxCIFS_troubleshooting#Wire_Captures
If you can open a bug at bugzilla.samba.org, you can upload the
captures there and won't need to send it to the mailing list. If you do
that, please cc me on it.
