For the connectivity test I chose ping, since it’s lightweight and unlikely to disturb any services on a device.

Ping using WMI

function Ping(host)
{
	var wmi = GetObject("Winmgmts:");
	var eStatus = new Enumerator(wmi.ExecQuery(
"Select StatusCode from Win32_PingStatus Where Address='" + host + "'"));
	return eStatus.item().StatusCode == 0;
}

The function Ping will return true if the host is online, false otherwise. Optionally, a Timeout parameter may be specified in the WMI query.
