Openvpn internet
You can either add your ISP's DNS as a "forwarded" on the Windows Server 2003 machine, or leave the stock "root hints" configured to allow it to resolve Internet names. In your OpenVPN server configuration, add the following line right after the 'push "dhcp-option DNS 192.168.1.1" line: push "dhcp-option WINS 192.168.1.1"
