How to connect 2008 Server to a second network.

First the scenario.  Have a network of 10 computers going thru a normal 24 port switch.  All 10 are running WinXP Pro and  log into a Win 2003 Server configured as a DC.  The DC handles the DHCP and DNS for the network.  The IP configuration is 192.168.30.XX for all computers. By design none of these computers have internet access.

Also, have a 2nd network of 6 PC's running WinXP pro.  These 6 computers are cabled together thru a Linksys Router (8) ports.  The (6) PC's do have internet access.  One of the (6) is connected to both networks by an additional cable to the (24) port switch and an additional NIC.  The 2nd NIC is configured to allow access to the 192.168.30.xx network.   Rest of the PC's have a single NIC with addresses of 192.168.1.XXX.  Router address is the standard 192.168.1.1.

Reason for the explanation:  I have installed a new server 2008 R2 that is required to be a part of both networks.  The (router network) for Internet access and the 192.168.30.xx network because the PC's on that network are running an application on the Win2K8 server using Remote Desktop to gain access.  The Win2K8 server at present is not configured as a DC.  It is basically a file server with the single application installed.  Also, it has (2) NIC's with the primary NIC  connected to the (24) port switch and configured for the network managed by the Win2K3 server.  No problems in this area.

Problem:  I have not been able to get the Win2K8 server on the internet as it doesn't see the router although I can ping the router successfully.  If I configure the 2nd NIC with a static IP of say 192.168.1.95 an error message is displayed saying that I have an IP conflict on the network, which I know does not exist.  If I configure the 2nd NIC to obtain a dynamic IP, the Win2K3 server  just provides another 192.168.30.xx address.   Question is what do I need to do?  Is there a way to bind the additional NIC to the 192.168.1.1 network or should the 2nd NIC be finding that network on it's own.  Both the NIC's in the Win2k8 server are connected to the (24) port switch.  Is there an additional role that needs to be installed on the Win2K8 server to accomplish the connection?  

I should also say that I just inherited the support on this account so I was not involved in the original set up of both networks.  For that reason I am having to feel my way along as to how these networks were setup etc.  It should be a relatively simple situation to set up but I  have managed to create a project out of this.  Any help will be appreciated.

I haven't posted a question on the board recently so if I am violating some protocol with the lengith of the question etc., just let me know what I should or should not do in the future.

Thanks, John Nelson

Just to verify... you are connecting both server nics to the 24 port switch, instead of connecting one nic to the 24 port and one to the 8 port?

Have you tried connecting one nic to 8 port switch and assign .1.x ip address and connect the second nic to the 24 port switch and assign .30.x address?

Yes, both are connected to the (24) port switch as there is not a direct cable from the router to the location of the Win2K8 server.  I thought it might work because I can ping the router successfully thru the (24) port switch.

Soulja:  I feel sure you are correct that it would work with a direct connection to the router from the 2nd NIC but at the moment I don't have that available. I think what let me down this path was the fact that I could successfully ping the router.  Do you think the only way it will work is with a direct connection to the router?

Yes, that's the way I see it. Another question, is the pc with 2 nics being used to connect the two networks? If so, then why do you even need to use two nics on the server?

Yes the PC with 2 Nics is being used to connect to the two networks.  1 NIC is cabled directly to the (24) port switch which would be the .30.xx network and the 2nd NIC is conected to a port on the router giving that PC internet access thru the .1.xx network.  I like the idea but how would this enable me to connect the server to the .1.xx network?

If that pc is connecting the two networks, I would just set one nic on the server to the .30.xx and set its default gateway to the ip address of the pc's nic that's connected to the 24 port switch. It looks like this pc is acting as a router between the two networks.

Now what you will need to do on the linksys router is create a static route that say to get to the .30.x network go to the ip address of the .1.x address of the pc with two nics.

The 2 NIC PC, I don't think is connecting the two networks.  One of the NIC's is directly connected to the .30.x network for access to an application that is on the Win2K3 server and the 2nd NIC is there strictly for internet access and is connected to the router for that purpose.  Based on this I not to clear on what you are saying.

Ok if that's the case then you want so setup your new server the same as the two nic pc.

OK, since I don't have a cable available probably wireless is my only other choice.
