CIFS: common internet filesystem, also known as server message block (SMB)
...
Desktop actions allow a client-side application on the Alfresco CIFS server to trigger a server-side action. The action is run in the context of the folder the application is running in. Files and/or folders may be dragged onto the client-side application, these are then passed as parameters to the server-side action. see http://wiki.alfresco.com/wiki/Desktop_Actions
Desktop actions are configured on a per filesystem basis using the file-servers.xml (or file-servers-custom.xml) configuration file. You can also specify content rules to apply to items such as auto-versioning.
Map network share drive \\servernameA\alfresco in windows or use smbclient in linux:
smbclient -U admin+ \\\\servernameA\alfresco
If it doesn't work, try the following command and one of the listed named should be the CIFS server name
nbtstat -a <Alfresco server name>
nbtstat -A <server ip address>
nbtstat -a <Windows server name>
