The questions were all technical. Event viewer, Sysprep, TCP vs UDP and ports examples, VPN, DNS and examples with DNS records, DHCP, IIS Permissions, Command tools, NAT, Registry, Global Catalog, Active Directory vs Workgroup, Troubleshoot a user who cannot access an internal site, and a tricky one : "Is it possible to change the RDP port?" The answer is YES through registry. I screwed up this one and probably cost me the next steps. So do get prepared well and try to give tight and to the point responses. Even if you know a subject well avoid to give lengthy answers as you will risk additional and harder questions. The interviewer was a technical person very polite and made you feel comfortably with the process. Good luck
