Why domain users account allowed to logon to servers directly?

Question

I'm using Windows Server 2008 R2 with ADDS.
By default, normal user account (domain users) should not be allowed to logon to Server directly, I mean the physical server or via RDP. They should get the message:
"You cannot log on because the logon method you are using is not allowed on this computer"
I had checked the GPO, under the Computer Configuration -> Windows Setting -> Local Security Policy -> Local Policy -> User Rights Assignment -> Allow Log on Locally, here only contains:
Administrators, Account Operators, Backup Operators, Server Operators, Print Operators
And, nothing set on the Deny Logon Locally.
But, tested that, those accounts with just Domain User Group are able to logon to Server!?
How or where should I check, to not allow normal user account to logon to server directly?
Thank you.

Hi,
>>By default, normal user account (domain users) should not be allowed to logon to Server directly, I mean the physical server or via RDP.
By default, standard domain user accounts can log onto workstations and member servers, and they can’t log onto domain controllers unless we allow them to do so via group
policy.
By default, standard domain user accounts can’t remote desktop onto other computers unless they have been added to Remote Desktop User groups of the computers.
Regarding allowing log on locally, the following article can be referred to for more information.

We can utilize group policy setting
Deny logon locally to prevent users from locally logging onto the targeted computers.
Regarding this setting, the following article can be referred to for more information.
