Restrict interactive logon on AD service accounts.


We are trying to restrict our service accounts in AD to do interactive logon process by pressing the CTRL-ALT-DEL key sequence.

What is the best way to do it?  We have all service accounts in an OU in AD.  Is it possible to use group policy to restrict that?  

Or should I do that in the machine level?

Please advise.

Is the goal to deny them from being logged on at all?

Haven't done this - but a good idea and I might now.  My first reaction is to try to create a Service Accounts group and then to create a group policy that restricts (explicitly denies) the right to interactive login

I have group all my service accounts into a service account global security group.  

should I just edit the domain policy and add the group into the "deny log on locally" and "deny log on through terminal services" under computer configuration>policies>windows settings>security settings>local policies>user rights assignment?
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Yes, this is most likely your best option.

In the GPO MMC snap-in, you can assign logon rights from the Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignments container.
