This is really a Windows problem I think, but maybe someone on this forum has faced it and solved it (or found unsolvable). I have a customer that must put their computers on a secured domain/network that they cannot put their PNA on. They want to put a second network card into the computer to hook up to the PNA. I do not know how to configure for DCOM communication in this type of setup, or if it is even possible. I do not want to revert back to GPIB interface because ii is MUCH software rewrite and much slower data transfer. Has anyone stumbled on this type of problem?
