To determine which domain controller you are currently using, you can use the command prompt or PowerShell on a Windows-based computer.
Open the command prompt by pressing the Windows key + R, then type cmd and press Enter.
Type the command "nslookup" and press Enter. This command will query the DNS server for the IP address of the domain controller.
Look for the line that starts with "Server:" and the IP address listed next to it. This is the IP address of the domain controller you are currently using.
Alternatively, you can use the PowerShell to determine the Domain controller you are using.
Open PowerShell by pressing the Windows key + R, then type powershell and press Enter.
Type the command "Get-ADDomainController" and press Enter. This command will return the list of domain controllers in the domain and the one that the client is currently using will be marked as the primary.
Keep in mind that, if you are connected to a network that is part of an Active Directory domain, your computer will be registered with a domain controller and will periodically check in with it. Therefore, you may need to check the domain controller you are using at different times to see if it changes.
In summary, you can use the command prompt or PowerShell to determine the domain controller you are currently using by running a command that queries the DNS server for the IP address of the domain controller.
