LANsurveyor can map your Active Directory infrastructure onto the physical infrastructure of your network. If you want to view just your Domain Controllers and your infrastructure, use Filters.
Click the Active Directory DCs option to discover the domain controllers on your network. By default, LANsurveyor uses the credentials of the person running LANsurveyor. If you want to use different credentials, click on the Authentication button then Add... to enter the credentials you would like to use.
Note: Active Directory only allows one user to be logged into a domain at a time from any given system. Therefore, if you are already logged into a domain as the LANsurveyor user and you would like to discover that domain, make sure that user has administrator access.
