Hi,

I have a client with the problem of connecting to Internet. I can ping any private or public IP address, but I cannot ping anything like www.yahoo.com or... gives error message. I have tried reinstalling windows and SP1. Uninstall any anti virus program and other firewall software. Also I am not able to obtain IP address automatically. I have to set it up manually. The DHCP is tested okay. The hardware is good.

Thank you very much for any help I can get.

Is the DHCP server handing out the correct DNS server address. Your inability to ping by name suggests a DNS problem either because of the DNS or an incorrect DNS server address on the client system.

Try doing the following on the system...

Re-enable DHCP on the client. Reboot if required.

Bring up a command window (Start/Run/CMD/enter)

Type IPCONFIG /ALL

Check the information to see if it matches the DHCP configuration.

If not type IPCONFIG /RELEASE

Then IPCONFIG /FLUSHDNS

Then IPCONFIG /RENEW

Hopefully it will get a response from the DHCP server. If not then there is a problem contacting the DHCP server which could be a result of any of the following.

- Client is behind a router that does not forward DHCP requests.

- NIC settings do not match speed and duplex of the connection (there are known issues with NIC set to auto detect not talking correctly to switches and hubs under XP)

- Bad NIC

Hope this helps...
