I've got a windows server 2016 DC, and another server 2016 machine. By default, the second machine had remote management enabled (showed up as "Enabled" under Server Manager > Local Server).
After joining the machine to the domain, remote management has been disabled. When I try and re-enable it in Server Manager, it shows a progress bar for a few seconds and then then does nothing.
I've also tried setting the group policy key "Windows Components > Windows Remote Management (WinRM) > WinRM Service > Allow remote server management through WinRM" but that appeared to also have no effect.
In the event viewer, there is a message about failed group policy updates - possibly related.
The processing of Group Policy failed. Windows could not resolve the computer name. This could be caused by one or more of the following: a) Name Resolution failure on the current domain controller b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller)
If it matters, both computers are in the same AWS subnet, and both have a public IP address, but security group rules prevent them from receiving connections from the internet at the moment.
