I have an OS X 10.7.4 Sever, which I'm trying to share files off of to Windows users. I've selected "Share with Windows clients (SMB)" in the Server app for each share, and I've opened ports 137-139 and 445 (tcp/udp) thru to the server. AFP shares work perfectly, as well as FTP. The firewall is off. However, when connecting, I get a "server does not exist / is not responding" error. Telnet into ports 137-139 fails immediately ("rejected connection"). How can I get the SMB server working?
