If you are running Debian just apt-get install linneighborhood
Package: linneighborhood (0.6.5-3.1)
An SMB network browser for Linux and X11.
This package allows users to browse SMB (e.g. Windows Network Neighborhood) networks under X, and mount/unmount SMB shared filesystems via a graphical interface. It is somewhat more network-efficient that other similar tools because it uses the proper protocol for identifying network shares rather than simply scanning IP address ranges.
In order for LinNeighborhood to work properly, you must have the smbfs filesystem compiled into your kernel and have a working Samba setup.
