The Domain Controller on the server uses the Microsoft Windows ‘Server Core’ Operating System. This means that you can’t connect to it directly via Remote Desktop Services. You can however perform all of your management and administration tasks from the Windows Management Virtual Machine which exists on each server and is named ZMANAGE.
You can find out the IP address of the ZMANAGE virtual machine from the Commissioning Console. (This Virtual machine has an IP address with the last octet being .160.)
Once connected via Remote Desktop Services to connect to the ZMANAGE virtual machine, you can then run all the standard Microsoft tools.
