installing visa 4.6.2 partially breaks network

[coder451]

I installed labview 2009 from dvd and gave it our serial number and activated it twice. After the reboot discovered a partially crippled network,

This means I can ping local ip's and I can dns and nslookup responses,

but browsing outside the localhost is broken. I repeated this install twice, then tried installing only NI-visa 4.6.2 from

a fresh download. This broke the network the same way. This is on win7 32bit. Either a system restore to an earlier point or removing NI-Visa fixes things back up. I have disabled windows firewall to make sure its not related to that.

Is this a possible issue with NI VISA or do I need to  look for a problem in this PC ? It shows no symptoms of Viruses or Rootkits that might be

intercepting the TCP/IP stack....

Hi Coder,

I haven't seen any other customers experience this issue, so I doubt that it is a problem with the driver itself.  What is the status of your network cards the same both before and after installing VISA?

Also, what if you try installing VISA 4.6.1 as a troubleshooting step?

I tried 4.6.0 and get the same problem, also did not install ethernet support. I will try each install option one at a time and see if anything works.

I did note in route after I install VISA it adds a 169.254.255.255 entry, maybe that has something to do with breakage. Routes seem to be whats really broken here.

Hi Coder,

How did this installation go?  And, also, what are you planning on using VISA for?

Cheers,

I found the problem was appearing that gateway in network settings was being set to 0.0.0.0, two entries appeared

0.0.0.0

192.168.0.1

if I do a route delete 0.0.0.0 I get an error message (windows not permitted) but then the net comes up.

I thought the remove / reinstall got rid of this but it appeared again after a recent reboot.

This first occured after installing labview 2009 which installs visa.

What do I use visa for?

It seems to be installed with NI Labview 2009 by default, or you can download it and install it separately.

I use the remote system feature which allows me to set visa up on another pc then access it from the PC with the development system on it.

At present the installation was successfull and I have to occasionally do

route delete 0.0.0.0 from a command prompt, then everything works including labview and any of the VI I write or run.

When 0.0.0.0 is in the gateway list, it prevents internet and network apps from accessing anything outside the immediate subnet.

I believe it is related to this discussion thread and KB:

You may not be using NI-DAQmx, but the underlying component "mDNS Responder Service" is also installed by NI-VISA and could be causing the same problem on your system.
