DNS issue or some things else?

[ChicagoTechNet]

XP laptop with D-link 650 wireless has been working fine until yesterday.

Symptoms: 1. At home with Linksys cable modem and D-link wireless router, the laptop can ping any public IPs but not web sites and IE gets “The page cannot be displayed”. Nslookup shows “DNS request timed out. timeout was 2 seconds.
*** Can't find server name for address 63.240.76.4:
Timed out, DNS request timed out. timeout was 2 seconds.
*** Can't find server name for address 204.127.198.4: Timed out
*** Default servers are not available
Default Server: UnKnown
Address: 63.240.76.4”

2. At home, other wired or wireless computers don’t have this problem.

3. If using other wired or wireless NICs on the same laptop, it works at home.

4. In the office LAN with Cisco router, the same laptop with the same wireless NIC, it also works.

What have been done: 1. try to logon another user.

2. ipconfig /lushdns or stop/start DHCP Client service to Purges the DNS Resolver cache.

3. Apply SP.

4. No firewall and run MSConfig to limit software running.

5. Reset cable modem and router.

6. Remove and re-install NIC with latest drive.

Still the same problem. Any suggestions?

Somebody else at home may be sending out bad packets. Double check your other machines at home. I know it sounds strange, but I've seen it. Good luck.

Can ping public IPs but not web sites

Symptoms: 1. You can ping any public IPs but not web sites. 2. The routing table and ipconfig look OK but you can't browse any web sites.

Resolutions: 1. Check the DNS, for example using nslookup to troubleshooting.
2. To test, disable any firewall. If it works after disabling firewall, re-configure the firewall and make sure the firewall doesn't black port 43..
3. Check the status of winsock.dll, wsock32.dll or download winsockfix to fix the problem
4. Also try to disable DNS client service if you don't have domain network or use ipconifg /flushdns to purge the DNS resolver cache.
5. Apply SP.
6. Try to logon another user.
7. Check Event Viewer for any errors
8. Remove and re-install NIC with latest drive.
9. Assign static IP, Gateway and DNS manually.
