I have a Server 2016 datacenter cloud server running in AWS that I "Locked Down" following the CIS L2 guidelines a year or so ago.
Recently I tried migrating the instance to a new account. Everything went smoothly until I got a message for activating windows. I have followed the AWS guidelines (which has always worked for me when dealing with other non-CIS migrations) and had no luck.
I am able to set the location of the AWS KMS by IP however I always end up with an error that no KMS could be contacted.
I tried doing the activation in windows on the local machine as well as in the systems manager of AWS using the "Automation" solution which also fails with a permission issue when I execute the automation.
Is anyone aware of a registry setting or group policy that needs to be reset during the activation process on the locked down instance?
Thanks for any insight you may have.
