Configuring CIFS

[thk]

Hi,

I have alfresco-5.0.d Community Version installed on a virtual machine (Ubuntu 14.04.2 LTS (64 bit)) of our server. Now I want to configure CIFS to access the Alfresco content like an Explorer Drive from my Window 8.1 PC.
I added in alfresco-5.0.d/tomcat/shared/classes/alfresco-global.properties the lines:

cifs.enabled=true
cifs.serverName=Alfresco
cifs.hostannounce=true‍‍‍

restarted the alfresco server and tried to a map network drive in my windows explorer.
Alfresco Installation directory on the ubuntu-VM is: \home\ota\alfresco-5.0.d
So can I just connect Alfresco as follows:
e.g. network drive: Z:
Folder:

\\<IP-Adress Ubuntu-VM>\\home\ota\alfresco-5.0.d‍

But it doesn`t work (message: Windows cannot access

\\<IP-Adress Ubuntu-VM>\\home\ota\alfresco-5.0.d‍

)
Is there anything wrong or missing in my configuration?
Has out Firewall to open some port and which ones?

Thanks for any help!

It seems that the problem why the folder of Alfresco is not visible in the Windows Explorer is that Alfresco is not integrated in the domain controller. How Alfresco can be integrated in a domain controller?

Thanks in advance for any help.

in the alfresco.log I see only:
2016-03-16 17:35:12,647 WARN  [org.alfresco.fileserver] [localhost-startStop-1] CIFS, Unable to get local domain/workgroup name, using default of WORKGROUP. This may be due to firewall settings or incorrect <broadcast> setting)
But I`ve no idea what can be wrong with the setting.
