LAN is operating but can't bring up a web page.

[Steph128]

Have a Windows 2000 machine that is supposed to connect to the internet through the office LAN. The cables are secure, and the connection is functioning. I cannot access the internet. Says that it cannot display the web page but at the same time DOES NOT say that I am not connected. Ideas, suggestions would be very helpful.

Can you get email on this box? If so look at virii.. else examine your firewall.

can you ping the proxy?

Start > run > cmd > in the dos prompt, type "ipconfig /all" and hit enter (without the "'s) > you should see listed a DNS server and a Proxy address.

first trying pinging the dns server
type "ping" a space, then the ip of the DNS server <ie ping 192.168.10.2> make sure you get sucessful replies

If you can ping then its most likely antivirus/firewall blocking your connection. try disabling what ever firewall your using and try again. If this doesnt work try the following:

Start>Run>Cmd

"netsh int ip reset reset.log"
"inconfig /flushdns"

Reboot

 

[Steph128]

I can successfully ping and the workstation does not have a firewall enabled on it. I still cannot get to the internet. I tried running the commands:
"netsh int ip reset reset.log"
"ipconfig /flushdns"

But nothing changed after I rebooted the machine.

Just some added information. This all started when we put in the new server. It could connect to the internet before we installed the new server but when I went to connect the computer to the server it kept displaying the message internet explorer cannot display the webpage.

Do names resolve properly? From a command prompt try tracert www.yahoo.com

Here is an interesting side note. When I took away the computer's static IP address it would not connect to the network. It would not access any other computer or even recognize that they were there. Is this computer a lost cause?

 

[Atavar]

You didn't mention if it obtained a dynamic IP address ok after you removed the static. Use ipconfig to check for a successful dhcp, make sure it got a valid IP address and gateway. Make sure you can ping the gateway.

If that doesn't work remove the NIC card, reboot the machine, reinstall the NIC, and see if it's any better. If not then replace the NIC. IF it is an on-board NIC disable it in BIOS instead of removing it.

 

[Steph128]

I replaced the NIC card and it still won't recognize the LAN without a static IP address. Is there some setting inside the computer that I am missing?? It had a static IP address before we installed the new server so that it could be remoted into by the IP address.

 

[Atavar]

You still haven't said whether it gave you a valid IP address with a valid reachable gateway. That is the very first step in troubleshooting.

 

[Atavar]

If you want more detailed help send me the outputs from 'ipconfig /all' and 'netstat -nr' and I'll take a look at it for you.

 

[Steph128]

No it does not give a valid ip address nor does it recognize the gateway. Sorry if I forgot to mention that.

 

[Atavar]

In that case I would first check the dhcp server by plugging a working box or laptop in to the same switch port and see if anything can get an IP..

if that fails then look at your network.

if the test box gets a good IP then rip out and reinstall the networking on the 2K suspect box.. make sure you have valid drivers for the ethernet card you are using.

Another good test (if another box does get an IP address) would be to boot the suspect box from a Linux Live CD, and see if Linux can get an IP address. The Live CD will not change anything on your hard drive, so when you remove the CD and reboot Windows will be back. Just don't click any "Install" buttons when you boot from the Linux cd. If Linux gets a good IP then you know your hardware is ok and you can look to your 2K configuration.

When checking the physical layer - don't forget the cable!

 

[Atavar]

Yes, look at the cable.. layer one problems are very common.
