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.
Viewing and modifying the settings for Windows network polling
To modify the properties of Windows network polling:
In the main menu, go to Discovery & deployment → Discovery → Windows domains.
Click the Properties button.
The Windows domain properties window opens.
Enable or disable Windows network polling by using the Enable Windows network polling toggle button.
Configure the poll schedule. By default, the quick polling runs every 15 minutes and the full polling runs every 60 minutes.
If the Administration Server is switched off or unavailable during the time for which the poll is scheduled, the Administration Server can either start the poll immediately after it is switched on, or wait for the next time for which the poll scheduled.
If this option is enabled, the Administration Server starts polling immediately after it is switched on.
If this option is disabled, the Administration Server waits for the next time for which the polling is scheduled.
By default, this option is disabled.
Save the properties of Windows network polling.
The properties are saved and applied to all of the discovered Windows domains and workgroups.
Running the poll manually
To run the poll immediately,
Click Start quick poll or Start full poll.
When the polling is complete, you can view the list of discovered devices on the Windows domains page by selecting the check box next to a domain name, and then clicking the Devices button.
