I joined a box to my domain using a static IP address (i.e. 192.168.5.11). I disconnected it from my domain and sent it to a customer. The customer received it and change the ip address and logged on with a domain account without any issues but the DNS record is not updating. It's still reading 192.168.5.11 in my DNS record. What do I do to allow the Records to update automatically if the clients IP changes.
