    Hi all:

    I have a WS 2003 machine connected to the internet via a cable modem.
    However for SOME reason the machine WILL NOT pull an IP from the ISP DHCP
    server, it cannot connect to the internet at all. When I run IPCONFIG it
    brings back some crazy IP Address that I never assigned and do not know
    where it came from....Has anyone seen this and/or have a solutions?

    Thanks.

    John.

    From a command prompt
    ipconfig /all
    may reveal something.

    Hi Guys:

    Thanks for the responses and sorry about my useless reply, bit of a harried
    morning! The IP Below, 169.254.36.232, is what I meant by a "screwed up" IP.
    I don't know where it's coming from, the network adapter is al set to
    DHCP...I have a Windows XP machine configured the same way and it works like
    a champ...

    John.

    When your pc is set to obtain an IP address from a DHCP server, and it can't
    find one it resorts to Automatic Private IP Addressing and you get an ip
    assigned in the range of 169.254.0.0-169.254.255.255 If you have ICF enabled
    it may be blocking ports 67 and 68 UDP which would cause this. The best
    solution is to install a broadband router between the cable modem and the
    private network.

    Hi Dave:

    Ah, so that explains THAT. However, I do not have ICF enabled so I wonder if
    those ports are blocked an by what?

    Also, I do have a router, but my issue is that I am trying to run 2 web
    servers using the TZO DDNS service, and also connect the servers to my LAN
    through a 2nd NIC card with a static IP. BUT TZO cannot find the path to the
    internet with 2 NICS, so I tried just plugging the machine into a hub
    working off the cable modem (I am allowed 3 IPs) but I am having these
    problems and I cannot figure out why.

    As I said, my Win XP machine has 2 NICs, one to hub, gets an IP no problem,
    and one to the router via a local, static dummy IP...

    For Web Server 1 I have the TZO service installed on the router and it
    forwards port 80 with no issues. For web server 2 I tried to install the TZO
    client on the machine, but it cannot work with the 2 NICs, so I disabled the
    LAN but for some reason the internet NIC just cannot get out. I tried
    uninstalling the NIC, disable/re-enable, ipconfig /renew, total power off of
    whole system including cable modem....nothing seems to work....

    Any thoughts as to what I should try next?

    John.

    From Windows XP do an
    ipconfig /all
    note the DHCP server IP address then on Windows 2003 (temp plugged into the
    hub)
    ping the DHCP server IP address
    What do you get?

    Is this a cabling problem? Perhaps you need a crossover cable where you have
    used a straight cable or vice versa. Check the LED's to confirm a
    connection. Also here's some guide lines that may help you resolve the
    issue.

    Something else to try; setup the router as a DHCP server then see if Win2003
    can get an IP address while plugged into it.

    Hi all:

    Well after HOURS of wasting time, I figured out the problem. I am using a
    hub plugged into my cable modem to allow 3 computers to get IPs from my ISP,
    but when the hub I ahve is sued this way, with an internet connection
    plugged into the "uplink" jack, jack 5 on teh hub cannot be used. That's the
    jack I was using and when I switched it out, VIOLA!!

    Wow, what a furstrating experience...

    Thanks to all for help.

    John.
