    I am trying to connect to the network, the network icon in the status bar shows yellow triangle with ! mark.

    When I place the mouse over the icon a box pops up to read

    Limited or no connectivity"

    I have used a Ping meter to check the net work point, it shows 100mbps.

    I have tried setting up another point around the building and patching this point to the hub. it works OK.

    I have now gone back to the other point and changed the ip and dns address to a fixed address.

    Now the yellow triangle is gone. But I still can not recieve packets. If I right click on properties. it show 92 packets sent 0 packets recieved!

    Suggestions please. :blink

    This is for work, I can not move the pc to another slot because there is only one point in the office!

    Have you got a laptop that you could plug in to test the cable?

    If it works you are getting narrowing the problem down.

    Something else is to try and do would be to disable the NIC and then re-enable it.

    UCHEEKYMONKEY,

    Try the following:
    • Unplug the ethernet patch cable from the computer and see if "limited or no connectivity" goes to "no connectivity."

    Hi,

    the fact that you are getting <some> connectivity when assigning your IP, suggests that the access point you are connecting to is not handing out IP addresses.
    What IP address and subnet mask are you using?
    Is there another wirless laptop there you could check the set-up on?

    The PC is desktop infact it's a Dell :rolleyes:
    onboard LAN configured to the net through RIS.

    I was wondering if it could be the users account privilages?

    Some users do not have full rights to all of the network unlike PC tech's who have full access and Aministrator access.

    what size business are we talking here? For the sake of ease, most places use DHCP, but static is not out of the question if it is a small number of machines.
    One other thing you could try is plugging your patch lead in to a known working outlet, ie one with a machine that is fully functional plugged in to it.

    Do an ipconfig /all at the command line. Is your laptop getting an I.P from whatever the DHCP source is on the network?

    Have you given the PC the right gateway I.P? If not then its probably not gonna get Internet access unless you go through a proxy. 8)

    Hi mate.

    We had this the other day, the aqnswer was that the DHCP server had run out of IP addresses. Therefore the NIC was sending packets but not receiving any.

    :D

    Sounds to me like it's got an APIPA address hence there is no other node on the LAN that can talk back to it :rolleyes:

    Do an IPCONFIG /ALL and post the results here.

    Its NHS, over 2600 Users and only 8 Hardware engineers and 2 very busy (get out of my way) Network engineer (who have got alot on their plate).

    The customer/user is a doctor and is very frustrated that she can not access the net. The computer works fine, we took it back to the IT dept. After connecting all the leads and RJ45 cable, we noticed it was connecting to the net with full access!

    Could it be the hub?

    It's not a laptop mate its a desk top Dell

    When I set the DNS and IP to automatic address, then no it shows the ip to be MS address with 169 at the beginning. But if I input a ip address starting with 128 and a DNS address and the alternative DNS address. the IP is shown in the cmd window

    ????

    It must be the HUB,

    Thanks AJ that sounds more like it!

    The network engineer told me yesterday there was problems with the network but don't tell the customers that!
    The network keeps Fluctuating, so maybe it is the server that's the problem.

    Although that still doesn't explain how I can logg onto the PC in the doctors office using the network logon and not the administror logon? yet I still cannot access the net through exployer?

    Also when the PC was RIS would the MAC address be assigned to the server? Otherwise the software wouldn't be on the PC?

    All machines/PC before going out have to hardware & software built, S/W is downloaded from the server after the MAC address has been assigned to the server???

    Any ideas?
