Scanner is hanging on specific devices 07 May 2013, 03:07

When scanning the entire subnet, there are 2 Liteshow Display devices that are the same model / NIC and the scanning sits on those entries with a ? and the scan never completes. If I stop the scan, they both show with icon that has a red x symbol.
Both devices are running the latest firmware.

Here's what is seen in properties:

Basic Info	Host Name	liteshow-confa.lcdf.org
Basic Info	HTTP Banner	
Basic Info	IP Address	[REMOVED]
Basic Info	MAC Address	00-12-5F-01-6B-FE
Basic Info	NIC Vendor	AWIND Inc.
Basic Info	Response Time	2 ms
Remote SNMP	Hostname	
Remote SNMP	System Contact	
Remote SNMP	System Description	
Remote SNMP	System Location	
Remote SNMP	Uptime	
Shared Resources	Folders	
TCP/UDP Ports	DNS Query	
TCP/UDP Ports	NBNS Status	
TCP/UDP Ports	NTP Status	
TCP/UDP Ports	TCP Ports	443, 80, 8080
TCP/UDP Ports	TFTP Status	
Workstation	LAN Group	
Workstation	Logged User	
Workstation	OS	
Workstation	Remote Time

Any ideas why this might be happening?

This tends to happen with some devices (I mean devices with a custom TCP/IP stack unlike regular computers). My best guess is that the device they don't answer a request in a timely manner and Windows waits indefinitely for it to complete.
