What is the most reliable way to get current AD domain-join information?...












0















With the advent of Azure AD domain join, several of the existing answers are likely outdated or incomplete.



What is the most accurate/reliable way to obtain the current AD domain status, and do it in such a way that I can tell if it's Azure AD, On Premise AD, or any other possible design (native UNIX Kerberos?)



Some of the keys I've found include:




  • HKLMSoftwareMicrosoftWindows NTCurrentVersionWinlogon

  • HKLMCurrentControlSetServicesTcpipParametersDomain

  • Configuration/Policies/Administrative Templates/Windows Components/Workplace Join


Aside from calling the win32 API, DsRoleGetPrimaryDomainInformation, I may also inspect the registry.




  • What is the most reliable method to get the primary domain join status?


Any additional information that relates to verifying the computer trust, connectivity "quality" to the domain controllers would be useful.

There seems to be two questions here:




  1. Find out if the computer is joined to a domain, and

  2. Find out what kind of domain it is.


I have a solution for the first question anyway. You tagged c#, so if that's what you're using, you can use Domain.GetComputerDomain. Put it in a try/catch block since if the computer is not joined to a domain, it will throw an ActiveDirectoryObjectNotFoundException exception.



But if it is joined to a domain, you get back a Domain object. That will give you some information about the domain, like the DomainMode. I don't have access to a machine joined to an AzureAD domain, so I don't know what that information looks like in that case, but it might be different.



Otherwise, for deeper information about the domain, you will likely need to use the Name of the domain and try to read more information from the domain itself.
