So somewhat of an odd scenario and I'm really hoping someone here can help and of course I greatly appreciate everyone's assistance with this!
I'm working with two Amazon Services EC2 instances, both Windows 2008 R2 64 EN. One of them is running AD and is using a dynamic IP due to the IP being changed each time the instance is stopped/started. I could assign a static IP, but the IP is released upon stopping the instance and I haven't figured out a way around that yet.
The second instance is simply the client, and I need them to be on the same domain. I've changed the host file in the client to point the domain name "sealtest.com" to the public facing IP of the AD DC, and iti s pingable. However, when I go to add it to the domain, it is unable to connect.
My plan was to simply update the HOST file anytime the server is stopped/started to reflect a change in the IPs, but use a dynamic DNS so that everything else is updated dynamically. Thus far, I'm uncertain why this wouldn't work, but I admit I'm also not the best when it comes to networking. Any ideas?
