Purpose of the Network Shares - SMB Tool

This tool scans your Windows domain and shows shared resources - This tool works best on pre Windows 10 computers. Win10 computers that are not master browsers will not show any results. Note: does not scan IP address ranges.

New in v11.84: SMB Scanner - scans a list of IPv4 addresses or hostnames and shows the supported SMB versions 1 - 3.1.1 of each target. Fast!

About the Network Shares - SMB Tool

The Network Shares - SMB Tool allows you to do several things (if permissions allow) including:

  • Shows visible shared resources on Microsoft network
  • Shows hidden shared resources on Microsoft network
  • Shows drive path of shared resource
  • 'Open' (writable) Share Detection
  • Operating System Detection as reported by NetBIOS and SMB (CIFS)
  • Network 'Browser' Status
  • Shows LANA and local network info with MAC addresses mapped to IP addresses
  • Filter responses by IPv4 address range
  • Filtering to reduce number of NetBIOS share responders on large networks
IMPORTANT SMBv1 Issue. As you are probably aware, the WannaCry and related viruses that exploit insecure SMBv1 have changed the way this tool operates. If you go into Programs and Features/Windows Features and uninstall SMB 1.0/CIFS File Sharing Support, it removes the 'Computer Browser' service. If that service is gone this tool will not work anymore - some information is shown but no shares are shown. In Windows 7, 8, 10 and the Server OSs you can use PowerShell commands to disable SMBv1 without uninstalling the SMBv1 support entirely. Please visit this Microsoft web page for those commands.

The screenshot shows the shares on the local network including hidden shares and disk drive paths. We have also include the ability to test those shares to see if they are writable or 'open shares' (in RED) which would indicate a vulnerability to worms and other malware. The lower window shows details about the systems that are sharing information on the network including MAC (Media Access Control) address, IP address, system type (ie. Windows 10, 8, 7, Vista, NT 4 Server, XP, 2003 etc.), network browser status (ie. master, backup, potential browser).

How the Network Shares - SMB Tool works

Crawls the Windows domain.
It starts with your current domain root and goes to each computer in the domain. If permissions allow, it shows shares and other information. Later operating systems like Windows 10 prevent unauthorized access to SMB information so we provide a login method.
