LabVIEW Stop Responding When Localhost Removed From Windows Route Table

[dannyt]

Hi,

I am working on Windows 7 using LabVIEW 2011.

I have a PC with two NIC cards in it, plus the onboard LAN connection and I am trying to run Iperf from one NIC to the other, through a wireless system.

To archive this I need to play around with the Windows route table to ensure to packets go out through the correct NIC. I found at one point in my experiments with this that, LabVIEW start reporting Not Responding messages, both when running my program and when in edit mode, LabVIEW was locking up for a few 10's seconds then continuing.

It finally dawned on me that this was after I had completely clear out the route table apart for two entries I had put in. On replacing the localhost entries 127.0.0.1 back into the routing table this Not Responding issue went away.

Does anyone have an idea what would be behind this behaviours ? I assume it is some sort of continuous poll to the Vi server by LavVIEW.

Cheers
