I am configuring a server for a friend of mine and his SOHO. I previously configured ADDS and print/ file sharing. They are now interested in VPN remote access to the domain. They have purchased a static IP address for the server and I am attempting to configure it. When I simply input the IP, gateway, subnet mask and DNS addresses the internet connection is not behaving properly anymore and workstations are no longer connected to the domain. I want to be able to leave their domain alone for the most part as their shares and user/computer settings are how they like. I also want the workstations to be able to continue getting their dynamic IP addresses as they previously have. Do I need to install and configure the DHCP role on the server to provide the 1 IP address to the server? There is only the 1 server I am slightly confused at this point and any help will be greatly appreciated.
