The Network Range Search task allows you to search a range of IP addresses for Windows workstations and servers to document. 

Unlike the Network Device Search Scan Task connections are made to the machines using WMI (Windows Management Instrumentation) and therefore SNMP is not required to be installed on the remote machine.

NOTE: This search task is typically used in a workgroup scenario. When using Active Directory, the recommended method for detecting Windows workstations and servers is the Active Directory Search agent.
