I need to install and configure Active Directory and DNS service on a remote Windows Server 2008 R2 which has a public facing IP, gateway and DNS. I don't really understand such network structure:
IP Address: xx.xx.93.158
Subnet Mask: 255.255.255.252
Default Gateway: xx.xx.93.157
DNS: xx.xx.64.10
I have experience on installing AD and DC, DNS services on local servers (which then the server becomes the DC for the local network) but I hesitate to do this on a publicly facing production server. Unfortunately I wasn't able to find a proper guide for my case. Would appreciate if someone could guide me on the steps I need to take so that I will not disturb the current network settings. (A little down time for installing the services and features is ok as long as I don't lose connectivity)
Thanks
