We have more Server with 2 network card.
first card have ip address, subnetmask and default Gateway 10.101.41.201, 255.255.255.0, 10.101.41.1
second card have ip address an subnetmask sample 10.201.9.201,255.255.248.0 an no DNS

Now, wenn copy a big file from one server zo another server and use

copy \10.201.9.201\d$\test\abc.bck d:\abc\test\abc.back,

so use the server BOTH network card for the copy job. But i will, that the server use ONLY the second network card.

I also have the same behaviour with robocopy, for example.

Does anyone have an idea what I am doing wrong?

    The server will only use 1 NIC to transfer out any file. As you are trying to copy file from 10.201.9.201, so it will be the second NIC to pick the job.

    You will have to do some extra configuration in order to let 2 or more NIC to do the file transfer out. Please read this blog for more detail.
