Do Computers authenticate against Domain controllers

I know that typing echo %logonserver% will show the DC I am authenticating with. but what about computers, I believe they have their own way of authenticating too. If so how do I find out to which domain controller a computer has authenticated with?

Thanks

the links above most of them talk about the same thing.

echo %logonserver%

well does this command used to see to which DC a user is authenticating to or to see the DC a computer is authenticating to ?

_ I am not sure at the first place if a computer authenticate to the domain. I know that a computer resets its password automatically.

What I believe is where the user is authenticated that will be the DC where computers secure channel is validated..

You can check the secure channel and which domain controller the computer account connected by nltest command.

nltest /dsgetdc:<FQDN Domain Name> /force

nltest /server:<Cluster server name> /sc_query:<FQDN Domain Name>

For a computer account the machine account password is important and it has to reset automatically by contacting every 30 days by contacting DC. for that secure channel is Important.
