About Windows network polling

During a quick poll, the Administration Server only retrieves information from the list of the NetBIOS names of devices in all network domains and workgroups. During a full poll, the following information is requested from each client device:

  • Operating system name
  • IP address
  • DNS name
  • NetBIOS name

Both quick polls and full polls require the following:

  • Ports UDP 137/138, TCP 139, UDP 445, TCP 445 must be available in the network.
  • The SMB protocol is enabled.
  • The Microsoft Computer Browser service must be used, and the primary browser computer must be enabled on the Administration Server.
  • The Microsoft Computer Browser service must be used, and the primary browser computer must be enabled on the client devices:
    • On at least one device, if the number of networked devices does not exceed 32.
    • On at least one device for each 32 networked devices.

The full poll can run only if the quick poll has run at least once.
