Using multiple NIC’s in Notes Client machine

I've searched high and low for an answer to this but this answer eludes me and I'm sure there is a relatively simple fix that I am just not recalling. Scenario: I have a machine running a Windows Server OS (Server 2003) that has 2 NIC's in it. Onto this machine was installed a single-user installation of the Notes client for one particular individual. The 2 nic's are for 2 completely different networks, and they connect to 2 very different switches, and there is no overlap from one nic to the other. I am trying to ensure that the person using the Lotus Notes client always uses a specific network adapter, and not the one that has no NRPC traffic on it whatsoever. Is there an easy way to accomplish this? Something that doesn't involve shutting down, or hardware profiles is preferable, but I need to know regardless. Please let me know, and thanks for your answers in advance.

Software/Hardware used:
Lotus Notes Client 7.0.2

    Thanks for your kind reply Jaideepkhanduja, but this is not a Domino or other Lotus server, it is only a Lotus Notes client installation. I am trying to force the Notes client to look on one network adapter for a path to the server, and not the other one. If you know of a way to do this, please let me know, ok?

    There is a notes.ini setting that we have used on servers to associate a particular Notes port to a particular NIC. I don't know for a fact that it would work for client but easy enough to try. In our ini, we had the lines below but nothing magical about the names. TCPIP=TCP,0,15,0,,12288 TCPIP_TcpIpAddress=0,10.1.254.174 vLAN=TCP,0,15,0,,12288 vLAN_TcpIpAddress=0,172.16.254.11 It may take a restart of the Notes client to pick the change up. Once it was restarted, you could go into Preferences and disable the port that doesn't talk NRPC. No guarantees on the client but worth a quick try.

    As TCPIP is a network protocol the server OS will know that the one NIC card has a subnet of x.x.x.x and the IP address of the Domino server the client is connecting to is on the same subnet. This would mean that to get the the server it has to go down the one NIC card to get server. Now if both NIC cards are on the same the subnet and IP range then this will not work, and I doubt there is anything by way of Notes that can be done.

    Thanks for the answers guys, please keep 'em coming. The client machine in question is a remote access client, and they are coming in off the internet via a pass-thru connection to a remote public IP address, just to add another wrinkle. The machine in question is using two very different IP addresses and subnets, so I'm basically trying to force that client system to go down one specific NIC for the Domino server, and not the other. Both cards are on separate IP ranges and subnets. As I said, the server is remote to this client, and access is over the internet to a pass-thru server via a public IP address on the pass-thru machine. Thanks!

    I don't think there is an answer to this. EAJewitt and Gabe9527 have pretty much put it in a nut shell. If the lotus client port can be assigned an IP on the preffered nic subnet then the emails will go down the correct nic. which is basically what they've suggested. Did you get any error from EAJewitt suggestion? What happened when you tried it? What was the reason to install a notes client on the 2 nic server machine? Does the notes client work?

    I really appreciate the input, and have only now been able to access that machine (it's a remote client in the Midwest, so access to it is based on their schedule and not mine). The machine is a double-duty system which ties to a plant monitoring system on a dedicated network via one NIC, and to the internet and our Lotus Domino systems via another. The two NICs connect to 2 separate and distinct switches, and the NIC for Lotus Notes goes from its switch to a router and then to the outside world. The plant network is not setup with a WAN link anywhere. Further, the Notes NIC IP addy is assigned via DHCP, whereas the plant NIC is a static IP. Also, these NICs are on two entirely different networks, IP ranges and subnets. EAJewett's suggestion works perfectly for the server, as there is a binding which must be done within the Server document, but the client does not care about an IP address, as evidenced by the lack of one in the Notes.INI file on the client system. Furthermore, as many clients use DHCP, there is no static parameter to be found in the Notes.INI, as my findings have affirmed. I fear that Gabe9527 might be right. As far as the client is concerned it may not be possible, but there has to be a simple way of enabling it somewhere. I just can't believe this capability is outside the reach of a Notes client. Thanks!
