This is my follow up question. I pulled the three CNC machines off my LAN
for now. Is there some way to connect my CNC machines to the office computer

Run the free version of ZoneAlarm on the CNC machines and all 3,
prohibit all IP addresses except from the office PC.

ZoneAlarm will ask the first time but check the "Always do this" and
click "Deny"
