You have a number of options, but it depends what you mean by 'remote log-in'. The easiest way would probably be to use a remote desktop application, such as gnome-rdp
which might already be installed (and if not, is certainly available in the repositories). If virtualbox is set up for bridged networking, it'll have its own IP address on your network which you can use to connect to it from either the local machine or from across your lan. RDP might not be turned on in the VM, though, which would make connection difficult - you'd have to access the console to edit that setting.
You may just want to browse the filesystem, you can install fuse-smb
package to be able to connect using windows own neworking filesystem.
what is your VM hypervisor ? kvm , virtualbox, vmware, xen , ....
virtualbox, and i have a another pc that is connected through lan....
