  1. Hello

    I was trying to turn off dhcp on my router and on on SBS 2003 Premium but di
    something horribly wrong and lost all network connectivity. At this point I a
    just trying to set it back to how it was but I am unable to see or be seen b
    the client computers
    I've tried many different things and was hoping someone here could offer som
    advice

    It would appear that you have two NICs in the SBS (there's not much
    point to Premium otherwise). You also have the same network address
    (192.168.1.) on both NICs, which is the cause of the problem. They must
    be different, since among other things the SBS is a router, and cannot
    determine which NIC is connected to the default gateway.

    If you are using VPN, or are likely to do so, then the 192.168.1.
    network is not a good choice, because VPN is also based on routing, and
    it's not unusual for clients to use that network by default.

    So connect to the Internet router and change its IP address to
    something like 192.168.37.2 (use a single PC/laptop plugged into it if
    you can't reach it from anywhere else, and of course you will lose
    contact when the network address changes.) Set the SBS external NIC to
    something else in that network, presumably the .1 address, and you
    should be back in business. You'll probably need to run the CEICW again.

    If you do want to change the internal network address, SBS has a Change
    IP Address wizard, which will do it all for you. You'll need to reboot
    the LAN clients afterwards.

    And going back to the beginning, you don't need to worry about the
    router anyway. The SBS DHCP server will operate on the LAN network
    only, the external IP address will be fixed, and the router can run a
    DHCP server without affecting the SBS. Just make sure the router pool
    does not include the SBS external NIC address. This is a useful way to
    work, as visitors' laptops can be plugged directly into the router and
    get DHCP information, and they will have an Internet connection
    without being able to reach the LAN.

    For future reference, Microsoft no longer maintains this newsgroup, and
    queries should now be posted to:
    http://social.technet.microsoft.com/Forums/en-US/smallbusinessserver/threads
    and you'll need a Hotmail or Live email address to post.

    I made some progress but I am still at a total loss. SBS can now see th
    internet but cannot connect to clients, or clients to sbs. Can some pleas
    provide more help
    I think the original problem of having the same ip on both NICs is stil
    there

    Yes, it is. You *must* change the network address, not just the last
    digit group. You *must* change either the LAN network address or the
    external NIC/router network address to be something other than the
    192.168.1. address that both have at the moment. Any of the
    192.168.xxx. networks will do, though I suggest avoiding 192.168.0. as
    well.

    The SBS Change IP Address wizard will do that for the LAN, but you must
    then renew the workstation DHCP leases, which is most easily done by
    rebooting them.

    Alternatively, you must change the SBS external NIC and the router LAN
    configuration to use another network address, as I suggested previously.

    You should also check that the workstations use only the SBS as DNS
    server, run the ipconfig utility to check that.
