This may be nothing to do with your Config Manager environment.
I assume your using KMS keys to manage your Windows OS licensing. Have you confirmed that your KMS server is working correctly?
You would normally only need to enter additional steps in your TS re: activation if you were using a MAK type key (as KMS server would automatically activate the OS upon first restart following OSD provisioning).
