Target Domain not seen as an option when trying to copy a GPO from a source domain.
说明
When you try to copy a policy and when it offered the choice of which domain to deploy the policy in, there are two domains missing. Everything appears to be configured and working fine otherwise. Those domains are visible under the live environment section of the console, but not in the copy wizard.
原因
By design, GPO copy is not meant for duplicating a GPO across domains.
解决办法
GPO copy really isn't meant for duplicating a GPO across domains. Creating a blank GPO in the second domain and then synchronizing, or exporting from one GPO and importing to the other would be a better way to accomplish this task.
If you are looking to keep these GPOs the same over the long term, then GPO synchronization is the best option.
