We are trying to get a BACnet connection up and we are getting an error with the local device.

It seems you’ve specified a BBMD to register with but are receiving a NAK response from it when the LocalDevice instance tries to register. I don’t know what would cause that response.

Ok that is kind of what we thought it was but we wanted to make sure it was on that front and not a driver issue. Wireshark confirms we are getting the NAK.
