Dell Optiplex 3010 Internet Issue

Hi forum members,

I have a Dell Optiplex 3010 desktop running Windows 7 Pro, 32Bit in my office. This morning I was unable to access the internet though I was able to print and access other network drives. I did a troubleshoot and found out that networks status changed from work to public. Error on network icon is "Unidentified network, no internet access". I did ping our router but timmed out. I can ping other servers & PC's on the same network but cannot ping the router or default gateway. I did the following

1. ipconfig /release or renew-did not work
2. ipconfig /registerdns/flushdns - did not work
3. Disabled network card or enabled it - did not work
4. Changed IP address from DHCP to Static - did not work
5. Updated, uninstalled, repaired network driver - did not work
6.Changed Speed/Duplex settings to 100Mbps, 1TB or Auto - did not work
7. Removed other networking services - did not work
8. IPReset All - did not work
9. Removed all Antivirus softwares -did not work
10. Disabled firewall

I am not sure about this issue. If anyone can assist me here. I will really appreciate him or her. I have been working on this issue for almost a day now.

Thanks in advance

Thanks Yard Dog, I have tried all the threads however same issue still exists. I really need help here..

Hi Yard Dog, I have run the command SFC /scannow without errors. Refer log file attached. Anymore ideas

Hi Yard Dog,

I just restarted the computer but same issue still exists..I cannot access internet.

Done that. It is already set to "Automatically Detect Settings". Still no internet access

Also I cannot ping the router/default gateway and DNS servers.... It is timing out..
