Two network adapters, one Linksys PrintServer and some bizarre beh

Discussion in 'Windows Small Business Server' started by Ricardo Marimon, Dec 10, 2004.

  1. I have my SBS with two network card (one external connected to the internet
    via a DSL modem, and the other internal connected to the local switch) up and
    running and doing some nice stuff. Yesterday I installed a Linksys
    PrintServer in the local network and was able to print nicely from the
    workstations inside the local network. When i tried to install the drivers
    in the SBS to print from there I was unable to make it work. Called Linksys
    and was told that drivers would nor work in SBS2003 but that I could try
    direct TCP/IP printing. Which I tried and more or less works.

    Here is the problem, if I disable the external network card connected, the
    one connected to the internet, it works, but once I enable the external
    network card, it stops printing. I can ping the printserver at 192.168.16.16
    with the external network card enabled or disabled, but I can only print and
    access the printserver web interface (http://192.168.16.16) when the external
    card is disconnected. It appears that the traffic to 192.168.16.* is being
    routed to the external card first, instead of the internal card.

    Any clues on how to solve this?

    Try moving the internal card to the top of the binding order in Network and
    Dialup Connections Window, Advanced Menu, Advanced settings. This will make
    all initial attempts to hit the inside card first. Actually, it should be
    set this way anyway, since the primary network is the internal network. Also
    insure you use itself as DNS on both cards. Setup a forwarder in your DNS to
    the ISP for efficient Internet resolution.

  3. I normally add a printer like this

    server
    add printer
    locak printer
    other tcp/ip
    add addresss
    add printer driver

    voila

    Don't add that printserver to the sbs, just have the server print via
    tcp/ip...works like a champ

  4. And that's how you should do it. You don't need anything special as long as
    the print device has an IP address....no drivers other than the printer
    drivers. Just create and share the printer as Susan suggests. Everyone
    should point to the server printer share(s) instead of printing directly -
    that way if you have to change anything, you change it only in one place, on
    the server.
    I'm not sure how this is related to your printing issue at all....what is
    your IP address info on each card? With both NICs enabled, run ipconfig /all
    in a command prompt and post results here. (ipconfig /all >c:\filename.txt
    makes this easier).

  5. I must have done something terribly wrong then, because I just did what Susan
    suggests and nothing happens. I can still ping the printserver device at
    192.168.16.16 but when I add the tcp/ip address and try to print I get a
    printer not found error. If I disable the external nic it works like a
    charm. This is so amazing...

  7. Here it is the "ipconfig /all". The first NIC is the internal one, the
    second NIC is the external one. Somehow I think that this printserver
    problem has to do with routing because it works when the external NIC is
    disabled. Somehow the route is assumed to go to the external card first and
    then to the second. I am also attaching the result from "route print" which
    I'm guessing might have something to do. If only I could understand what it
    says ;-)

    Thanks agains for all your help...

  8. Your printserver is at 192.168.16.16. Is that address excluded in the DHCP
    scope? Get rid of the cantv.net dns suffix on your nic properties.

  9. That address, actually from 192.168.16.10 to 192.168.16.19 I have excluded
    from the DHCP server. I would like
    to use those for PrintServers (if it ever works!). As for the cantv.net
    suffix, that comes automatically from my
    ISP since I need to have a dynamic external IP address. I'm updating this
    external IP address via dyndns.org.
