two ethernet adapters = troubleshooting

[Josen]

We are developning an application in LabVIEW 6.02 which controls a Logic Analyzer (HP1670D) via telnet and ftp. The medium between the HP and our PC(NT-4) is a TP- or a coaxial-cable.
In our PC we have two ethernet adapters, one that is talking with the LAN and one that is suppose to talk with the HP throw our LabView-application. However we are not able to use the secondary ethernet-adapter with LabView. It seams like that LabView is not able to handle two ethernet-adapters, some kind of conflict or delay is raised during the communication.
Other applications (i.e ftp-programs) handle the communication with the HP without any problems.
The LabView-application works great against the HP if we only use one ethern
et-adapter.
Do you know how to solve or where to find any solutions to this issue ?

I'm not sure if I can help, but I can tell you that I use 2 NICs with LabVIEW all of the time and have no problems. We configure the card on the LAN to get its IP from a DHCP server and we specify the IP of the second NIC. We generally use something like 192.168.xxx.xxx and make sure that the subnet (third set of numbers) is different from our LAN. The products that I test have and ethernet connection and I ping and telnet to them. Our configuration is Win NT 4 and LabVIEW 6 and LabVIEW 5.

Josen,

Unfortunately, I don't really have an answer. However, I AM having the exact problem you encountered in April. If you have discovered a solution to this problem, I would be very greatfull if you could share that information with me.

Thanks,
