Ok, can you please tell me if this a new problem ? reoccurring problem? For the pcs that cannot reach the internet what error do you get when you attempt internet access? Also on the pcs that cannot access could you please go to the command prompts and type, IPCONFIG/ALL, and paste the info on here.
Thanks
Matt

Have you ran any spyware scans on these machine recently?? Have you been messing around in the registry? You can try this Winsock fix it is a free tool it might be able to restore you connectivity.

Ok, well I should still like to see the ipconfig/all output from the non-working machines. I would suggest you have a networking issue. I can help you out further if you can provide me with the details. I would also like you to ping www.google.com and tell me that exact message you recive in respone to the ping - this provides me with alot of networking information
Thanks
Matt

Try and determine if this is a names resolution issue or a connectivity issue. Since pinging by name did not work, ping by IP address. Ping 64.233.187.99, which is google.com. If that works, look for a DNS problem with 10.0.32.20. If it doesn't work, let me know and we will troubleshoot further.
Thanks for the information. You ip configuration is correct, you computer, DNS server, and Default gateway are all on the correct subnet. Your pc has resolved a DNS name so I would say that is fine also. Do you get a reply when you ping 127.0.0.1 ? can you ping other pcs on your Internal subnetwork? I would like you to ping your DNS server and default gateway please and tell me if they reply in a timely fashion. could you also do a tracert www.google.com for me please.
thanks
thanks
Did you try the Winsock fix on one of the machines?
ASKER
Good Morning...
ping to 127.0.0.1, 10.0.32.107, and DNS = TTL 128.
ping to 64.233.187.99 = Request timed out.
Tried Winsock on both machines = unsuccessful.
Tracert = unsuccessful.
Thank you.

AMLI:ACPI Bios is attempting to read from an illegal IO port address(0x71), which lies in the 0x70-0x71 protected address range. This could lead to system instability. Please contact your vendor for technical assistance.
Don't know if this helps at all. I wouldn't think so because I have done everything except fdisk.

ping to 127.0.0.1 - this means TCP/IP is functioning correctly on your pcs. I belive the DNS server is performing recursive quries on the pcs behalf correctly also.
Tell me, what device are you using for internet connectivity?e.g. router, and are you the only one who administers it? Communications on your LAN are working ok. Can you ping
Default Gateway . . . . . . . . . : 10.0.32.40 ?

ping .40 TTL = 64
Communications on LAN are good.
I am the only one that administers the network.

So your pcs can also see your default Gateway, good. Have you tried putting the 2 non working pcs on difference Switch ports ? I know Lan comms are ok, but sometimes low end switches can play games!
ASKER
Yes, I have done that too, and I have reset the switches.
Ok. Are you using a proxy server? Have you specified a proxy server in internet explorer options for these machines? The fact you cannot ping public IP addresses, but you can ping internal hosts, including your default gateway would suggest to me there is a problem at the router perhaps. I am unfamiliar with Cayman, however I am experienced with Cisco routers. On these it is possible to deny traffic on a host by host basis, I am not sure if this is possible on caymen kit. Has this problem just started happening recently? how long has this been happening? Earlier you kindly did a tracert for me, however you did not show how many hops it made. I would be interested to see how many hops are made.
thanks
thanks

No proxy server. A Cayman Router is what I call a generic router supplied by SBC (now AT&T). The router has worked great for the past year and a half. Thi sproblem began last week Monday for one user, and then this week Wednesday for the other user.
Thanks for your continues attention!!!

No probs, this is a tricky one! If you could kindly do a read out of the full tracert results to www.yahoo.com (for example) that would be great. I am also wonder if maybe your pcs have picked up a virus or some nasty. Are you receiving the same error ""This page can not be displayed." on both non working pcs?
thanks
thanks
ASKER
yes, i receive the same message...I will be back in about an hour and a half
Thanks again!!!!!!
Thanks again!!!!!!

Tracert results were:
1 * * * Request Timed Out... 30 times...which is the maximum number of hops.

if thats all your arp cache has in it, it doesent know the mac address of the default gateways interface!
here is my pcs arp cache;
Interface: 172.22.0.2 --- 0x5
Internet Address Physical Address Type
172.22.0.1 00-13-5f-6a-d6-a1 dynamic << My Vlan1 Interface (default gateway)
172.22.0.20 00-02-b3-8e-1a-1c dynamic
If you can find out the mac address of your routers internal interface you could try adding that statically to your pcs arp table and see if this helps. Other than this I am currently out of suggestions :-)

Cool...
I'll try that. I just entered arp -a on my pc and it came up similar to yours.
Have a Great Weekend!!!

Cheers man.
The easy answer: Take a look at proxy definitions. Go to Tools / Internet Options / Connections tab / Lan Settings. Compare the settings. Maybe you find something different and the reason for the problem.
