Guest Brad Posted September 5, 2007 Posted September 5, 2007 I have a small office with one server 2003 running as the Domain Controller and DHCP and routing services. It is currently multihomed and works just fine. The layout is: internet -> linksys router -> Server (external nic) -> Internal Nic (server) -> switch -> Client PCs and printers. I've been reading that multihomed DC's are not a good idea. If I change my network to be non-multihomed, what handles all of the routing. Say I want to RDP into each client PC, the PCs are getting their IP address from the DC since it is a DHCP server, the linksys won't know the client IP address. So does the Linksys pass the external requests to the server, then the server passes the requests to the client PC. In my mind, the server is no longer "in charge" if it doesn't have the direct connection between the router and the internal network. The client PC's have their DNS pointing to the server. Any guideance is appreciated.

Here are a couple of ways to launch Remote Desktop sessions on internal PCs: a) By setting up a VPN. The RDP client will then behave as if it was connected to the internal network, which will enable it to reach the RDP host by its NetBIOS name. b) By assigning fixed internal IP addresses and individual RDP port addresses, e.g. like so PC10 192.168.55.10 Port 19010 PC11 192.168.55.11 Port 19011 PC19 192.168.55.19 Port 19019 You need to create one tunnel for each PC in your router/ firewall. You also need to modify this registry location on each RDP host to set the desired port number. It is set to 3389 by default: HKLM\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber Remember to reboot the PC after making the change. On the RDP client you must use this command: mstsc /v:aaa.bbb.ccc.ddd:19010 where aaa.bbb.ccc.ddd is the external IP address of the RDP host and 19010 is the chosen port number.
Guest Robert L [MVP - Networking] Posted September 5, 2007 Posted September 5, 2007 Re: help me understand Correct, it is not recommended to use DC as a router or running on a multihomed computer. What you can do is setup switch between the router and the network. Setup DNS and DHCP on the DC. If all computers and router are in the same subnet. you should be fine.
