Environment

Product Family: Software
Product: Venus 1500 V4
Component: Computer Name
Control System: Venus 1500 4.20.4, 4.22.3

Cause

Computer's name is all numbers or starts with a non-alphabetic character causing Fusion's algorithm to throw random and incorrect IP addresses.

Resolution

Rename the computer to start with a letter instead of a number and then completely uninstall and re-install the software if necessary.
