Once you run dcpromo you no longer have access to a local accounts and won't be able to log on locally. Or run gpresult. It will tell you the server role.

Hi group, How can I determine if a machine on my network is a domain controller? The machine in question doesn't have netbios over tcp/ip enabled (I'm guessing), so my trusty nbtstat commands won't answer this question for me. I noticed at my new job that my groups local development server has a NETLOGON share. It'd be odd for this server to be a DC, but that share sure is suspicious! Let's assume that I have admin rights on my local machine but no other machine on the network. Thanks
