[Samba] Strange issue after upgrade

[Andrew]

Last weekend I upgraded my RedHat Enterprise server from Samba 3.0.2 to
3.0.4 and now my Mac clients are not seeing one of my shares. Normally a Mac
client can select Go->Connect to Server in the finder, connect to the server
and then they will get a list of 2 shares. Now one of these shares is not
showing up (The Company_Share) but the client can still connect to the share
if they add the share to the end of the server address field.

In other words instead of selecting Go->Connect to Server connecting to
smb://server.domain.net then selecting one of the shares from the drop down
list the user now has to connect to smb://server.domain.net/Comany_Share
(Typing in Company_Share manually). Does anyone know why this happened?

Here is my config:

[global]

password server = dc0.domain.net dc1.domain.net
