CIFS on Windows 2003

[mojo-jojo]

System:
Windows 2003 x64
Alfresco 1.2.0 final
MySQL 4.1
JDK 5.0 Update 6

All of the functions work (WebDAV, image transformation, document conversion, etc.) except for CIFS access.  Should the default configuration work right away?  When I try to access \\ALFSERVERNAME_A it can't be found.

I have included Win32NetBIOS.dll in the path and Alfresco finds it just fine.  I do receive this error though.

13:15:12,842 ERROR [org.alfresco.smb.protocol.mailslot] HostAnnouncer initialization error
org.alfresco.filesys.netbios.win32.WinsockNetBIOSException: 10047:CreateDatagramSocket - Address family not supported by protocol family

   at org.alfresco.filesys.smb.mailslot.HostAnnouncer.run(HostAnnouncer.java:248)‍‍‍‍‍‍

Is this why it's not working? If not, what steps do I need to take to make the CIFS access work on a Windows server?

Thanks.

I am running Version: Community Network - v1.2.1 and it is a fresh install

I made sure to edit the config to:
<Win32NetBIOS api="netbios"/>

I was running 1.2.0 when I first starting having problems.

The server is a Windows file server if that makes any difference.
