Configure my OpenVPN for DHCP

I am running OpenVPN 1.35 on my Windows 2003 network. My OpenVPN server "VPN Topology" is configured as a Layer 3 (routing/NAT), so when users connect to my OpenVPN server, the OpenVPN server is dispensing an IP address. My "User Authentication" is set to PAM. Here is where I need your help: When users connect to my network, I would like for them to have the appearance that they are connected to the network locally. Meaning, they would have an IP address dispensed by the Windows 2003 DHCP server and record the machine name in the DNS. (I can explain why I need this later). I believe this may be done by using bridged mode on the OpenVPN, but would rather defer to an OpenVPN pro for the answer and to log in to make the necessary adjustments. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
