So I'm relatively new when it comes to working with servers, and I'm going through the MP 70-640 exam training kit. I came to this one lab where I need to transfer an Operations Master Role. I have a server(Server01) that runs ADDS and is a domain controller, and I have another server (Server02) that is also running ADDS and is joined to the domain. It tells me to right-click the domain and choose "change domain controller" and select Server02 on the "Change Directory Server" dialog box. The problem is Server02 doesn't show up. I try to type it in manually but it says the status is unavailable. Maybe this is an easy fix, or I'm overlooking something, but can anyone help me out or have an idea what I'm doing wrong? I am also using VMWare for my virtual network.
