Error -50150 when trying to reserve cDAQ 9184 ethernet chassis in MAX.

[Alex_White]

When trying to reserve a cDAQ 9184 ethernet chassis in MAX, and am receiving the following error.

The network device could not be reserved. The error report from the device driver is as follows:

Status Code: -50150
The software has entered an unknown state - usually a result of a cascade failure induced by an unexpected series of state inputs. The operation could not be completed as specified and you should immediately terminate all further transactions if you are able to do so.

I am using NI MAX + DAQmx 21.0. The chassis is connected directly to the PC via ethernet. I only experience this issue when I am using my company issued computer, which has a variety of network/firewall settings changed, virtual network adapters from VPN services, and probably many other network related changes that I'm not aware of. On a PC running plain out of the box windows 7, I can connect to and reserve this same chassis using the same version of MAX + DAQmx with no problems.

I've gone through the steps listed on this troubleshooting page.

I've tried disabling all network adapters except the one connecting to the chassis. I've worked with my company IT department, and they claim that all the ports listed on the troubleshooting page have been opened for me. I've tried factory resetting the chassis.

What other settings on my company issued PC could be causing this problem??

Did you find a solution or the root cause for the problem.

We have the same status code / error with our TSN chassis (9185 and 9189). On some computers it is working, on others it does not. We have no idea why.
