[Samba] Samba 3.5.10 and Windows 7 DNS Issues

[David Greco]

Having a hard time getting Samba 3.5.10 on Centos 6 and Windows 7 to play nice. The Windows 7 clients are on a windows domain, DFBFL.ad.foo.com, but the Samba server is not a member of this domain. Security level in samba is set to USER.  I can successfully browe and access samba shares utilizing the IP, \\10.70.147.151\<file:///\\10.70.147.151\>, but cannot using the DNS name, \\hhl-webdev\<file:///\\hhl-webdev\> or \\HHL-WEBDEV\<file:///\\HHL-WEBDEV\> or \\HHL-WEBDEV.DFBFL.AD.FOO.COM\<file:///\\HHL-WEBDEV.DFBFL.AD.FOO.COM\>. Hitting it via DNS name results in continual password prompts.
