Problem with Windows Server 2019 core mode evaluation - how could I activate the 180 days trial period?

[grunter]

Hi, I'm using Windows Server 2019 core mode with AO 3.00.
I've downloaded Windows Server 2019 standard evaluation iso from the link that we could find in the AO pdf guide at page 4.
The question is how could I activate the 180 days trial period?
Infact, without activating the trial period, windows server is shutting down randomly, as we could read in the "windows_server_2019_setup_guide.pdf" at the bottom of page 6
"If you are using the Trial/Evaluation Edition of Server 2019, you need an active internet connection for the System to activate itself online. If the system cannot activate itself online, it will not run for the full trial period and will start shutting down the machine automatically if idle".

Is there a command I could run to activate the trial period?
Have I got to do a configuration in order to activate Internet connection on windows server 2019 core?
Thanks.

Unfortunatly I leave internet connection on, but it doesn't activate the trial periodo, because after a while the computer shut down.
I try "slmgr.vbs -ato" but it responds "Error: Product not found".

Could the problem is the fact that I installed AO before the connection to internet?
Do you think that launching the Service Tool and disabling all the optimizing lead to the possibility to activate the trial period?
Thanks.
