I have mounted samba shares before with other winxp boxes in my network by using

mount -t cifs //computername/share /mnt/computername -o ip=192.168.1.x and it worked fine.

However, I setup Virtualbox on this Slackware 12.2 computer and have added a windows xp pro sp3 virtual. On this virtual, I setup a share, enabled file and printer sharing, made sure the windows firewall allowed file and printer sharing and rebooted.

Then I tried using the above mount command above, but it says

mount error 111 = Connection refused

So I know it's probably a firewall problem. The thing is, all of my computers are in the 192.168.1.* network. However, this windows xp pro sp3 virtual is in a different network 10.0.2.*. This windows virtual can ping a computer in the 192.168.1.* network and the slackware 12.2 host can ping the windows virtual. They are both internal IPs and are both on the same subnet 255.255.255.0. However, since they are different ip ranges, are they really on the same subnet? I mean they can ping each other so I'm assuming they are.

Anyhow, I'm thinking that the fact this windows box is a virtual running on a different ip range is what is complicating things.

When I run nmap on the windows virtual, ports 139,445 are closed. Why is this so, I when through setup home network wizard, and make sure the windows firewall had file and printer sharing checked. I also created a folder on the desktop and enabled sharing on it.

Any ideas?

What kind of Virtual Box networking are you using? The default is NAT; perhaps it would work better with "host interface"? I think that will also give your virtual xp a 192.168.1* address like everyone else.

Yup that was the problem. So then if you select NAT, it puts the virtual on another network? Same subnet? I could ping across networks, and the virtual had access to the internet with dns, but then why couldn't I mount the cifs?

Eh, I'm not sure; part of the point of NAT is to hide behind it. The VirtualBox docs also list some limitations of their NAT - so I don't know if it's specifically their implemaentation or not.
