  • Windows Server 2008 R2 with 2 NICS problems

    I setup two NICS on my windows server 2008 r2. The first NIC receives the internet connection from internet 2-this multi static. The second NIC is connected to the switch that enables the PC1 to PC4 access the application I installed in the server.
    My problem is when cable from switch is connected to server. The server will detect the public IP of the internet 1-the dynamic IP NOT the internet 2. But when I disconnect the cable from switch to windows server that's the time that it will detect the static ip from the internet 2.I want the server to detect the public IP of the internet 2- the static because the other branch will dial this IP in order to establish remote access to the server. Is there a way to fix this things that even if I plug the cable from switch to server it will still detect the static ip of internet 2 not internet 1?

    The second problem is the speed of the internet of PC1 to PC4. Every time I connect the cable from switch to server. It will slow down my connection that sometimes I cannot open a website. The internet is OK if I unplug the cable from the server. I seems that the server will get all the internet? Is there a way so solve this problem?

    Please give me some help in this matter.

    It sounds as if you have VLAN mismatch issues in your switch configuration as a minimum, but we need more info to be sure.

    *-What kind of setup do you use to talk to the internet (hardware, IP info)
    *-What route info does the server hold? (issue 'route print' from a cmd line on the server)
    *-What's your address range for the PCs and the 2nd NIC on the server? Are they all fixed addresses or do you use DHCP?
    *-Is your server acting as the router for the PCs to access the internet?

    Pls post your answers here. A drawing might help.
