I was given the contact info for Andre, a technician who was supposed to come out and do our mastering. He was immediately concerned that we had not diagnosed the solution correctly. There is little reason that changing an IP address and changing it back would cause an entire system to break to the point to re installation. So after exchanging some emails and a phone call we were able to get the system back to working order without doing a full restore.
We looked at DV2DRV the driver that was giving the error in our log. which is associated with DeviceNet. As said above device net was disconnected and not in use but this driver was still giving an error. So we uninstalled the DeviceNet driver from the I/O configuration window, reconfigured our I/O and did a cold reboot. And TAA-DAA the problem was solved. We still had to remaster but it's much better than having to re install windows and KRC.
We can re install the DeviceNet drivers when we need them. But for now we fixed our problems.
