How am I able to access a network share without samba running?

I will elaborate. I have installed OpenSuse 12.1 Gnome Desktop inside VirtualBox.
I attempted to setup Windows Domain Membership through YaST but it hung (I think because the Firewall was blocking it as I had not allowed the services through at that point) so I just did a hard reset on the VM because I could not get the hung session to close.
For no apparent reason I opened up Nautilus and manually entered a path to a network share (smb://server/share) and it responded asking me for my user name and password. I entered the correct domain, my name and password and I was in.

I’m confused because I did not think I had setup anything on this VM yet and was expecting a failure to find any network resources. I’m attaching my systemctl output for someone to please examine and hopefully give me some insight.

I just thought that there was no way to use smb without smb first running.

Also; the reason I’m posting just to be clear is that I would like to know what protocol or service is allowing me to access my network share.

Thanks,

But aren’t you saying the windows box is serving the files
So you can access that with any PC if you use the correct protocol.

It is a Windows machine that is serving the network share. I guess maybe I need a networking 101. I thought that a clean install of Linux would not be able to connect to a share unless the user (me) setup samba or some other means to do it. In this case all I did was put in the address to the share in nautilus and it worked after authenticating my information.

Are you saying that without any application setup on the Linux machine, it can connect to network shares?
The smb service and nmb service are listed as off on all run levels.
What is running thats allowing me to get the connection from the Linux side? I feel like I may be asking the wrong questions.

Only the server needs it running.

So yes to this

Are you saying that without any application setup on the Linux machine, it can connect to network shares?

Thats good to know I guess after all the years I’ve struggled with Samba.
KDE using the Dolphin (window manager?) and Gnome using Nautilus both have Network links on them. So let me ask this.
What is required to populate a Domain or Workgroup in those areas? You have Samba Shares, and two others I can’t remember right now.
In order to populate the Samba Shares directory to show a Domain or Workgroup you need to setup Samba on the client correct? Or is it just allowing NetBIOS through the firewall?

It’s not necessary to offer a service (which is a long-lived daemon) to be able to use the protocol as a client. Just like you do not have to run a web server to use the HTTP protocol from web browsers, you do not have to offer a SMB service to be able to use SMB shares as a client.
