    Dual NIC's and Networking Issue

    Good Morning,

    Just before i start, I would like to explain that I have searched the net and these forums extensively prior to this post :ange:

    On to the issue at hand; we have one powerful workstation that we use to process videos at work and the storage on this has filled up very quickly. We wish to add a second PC on a seperate network card in order to move the videos to, after processing (thus not impacting on the corporate domain the PC is on).

    I have configured the first PC with the following TCP/IP settings (for the new card);
    IP - 192.168.110.101
    Subnet - 255.255.255.0
    No Gateway

    The new PC is as follows;
    IP - 192.168.110.102
    Subnet - 255.255.255.0
    Gateway - 192.168.110.101

    Now, the second (new PC) can connect fine to shares on the domain PC when I use domain credentials to authenticate with (I expect it would also work with local accounts too) but the problem occurs when I try to connect to the new PC from the domain one (using \\192.168.110.102). I get the error message "no logon servers available to service the logon request".

    Does this mean that the PC is trying to authenticate on the domain only and it struggles to find the new PC on it (which I know it would struggle to do as it hasn't joined the domain at all and never will)? If this is the case, can I actually force the PC to send all requests to a certain IP through one particular NIC? From my research this could be the route adding that is mentioned quite a few times.

    Anyway, over to the experts now.

    Thanks for reading.

    I don't really understand why you've set the default gateway of the 2nd machine like that. If you're just connecting via a crossover cable, I'd leave the default gateway blank. What are the settings for the rest of your corp network? Assuming it's 192.x.x.x, I would set the 2nd card and 2nd server to use:

    10.0.0.1 and 10.0.0.2
    mask 255.255.255.0

    Just to avoid any potential conflicts.....

    You can connect 2 windows machines together with DHCP enabled and and they'll configure the connection automatically with APIPA giving you a 169.254.0.0/16 address.

    Re: Dual NIC's and Networking Issue

    Is the 2nd PC (the new one) also part of the domain? If not you would have to connect with a username from 192.168.110.102

    Have you tried setting the gateway in NIC2 on PC1 to be 192.168.110.101 (telling it to use itself to get to other addresses in the network range)?
