Cannot browse the Internet

Have a laptop (Windows 7 x64 standalone)which cannot browse the Internet.  Troubleshooting steps taken:
-Cannot ping domains by name only by IP address, but nslookup of various domains are successfully.
-Tried from both wireless and wired networks - same result
-Checked "hosts" file, no unusual entries
-Winsock reset procedure
-Was using as DNS server, tried Comcast DNS servers, but nslookup works so it isn't the DNS server.
-Inserted an entry in the "hosts" file -  (then tried to ping, no luck)
-Uncommented localhost and pinged localhost still get "Ping request could not find localhost".

Try the following

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer

Let us know if that helps.

If you have a another laptop you can plug it and check if it works there.
If it works check the IP Configuration of that machine and on the one it is not working

Also check with the different browser and setting under the browser.
If DNS is checked then it is fine. If you are using internet on home network check on properties of device(Router) if there are no restriction on your laptop particularly.
Take the above advice and flush your DNS cache. Try using an 'Incognito' window or 'Private Browsing' window, depending on your browser and see if the pages come up.
IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

No luck.

Nothing to do with the browser.  Cannot ping by domain name.  Ping looks at the hosts file first I believe, but if I create entries they don't work even local ones.  Nslookup tests from the first DNS server first and that works.  Tried the "netsh int ip reset", that is what I listed as winsock reset.  However, tried it a second time.  Apparently, something is corrupted.
Have other computers on the network both wired and wireless that are working fine.
Can you supply the domain name? I don't want to ask for too much information, but I can troubleshoot better with at least that.

Just trying to ping "" or "".  Resolver problem, but nslookup works.  May be time to reimage.  Would like to know what is causing this however.

go into device manager, delete your network adapter and reboot, repeat your tests it may be resolved.

And report the results....
can you still download updates?  i had such a case on a new install, and all i needed to do is waiting for the updates to install

 i assume you have no errors in device manager - or in event viewer, related to this?

Open cmd.exe with Run as Administrator and run SFC /SCANNOW twice. Shut down, start up and test.

If that does not work, you need to consider a Windows 7 Repair Install. For this you need the Windows 7 DVD for the system. Here is a Seven Forums tutorial to assist.
WebccAuthor Commented:
Yes I already tried the SFC utility last night.  Will run the repair install.
JohnBusiness Consultant (Owner)Commented:
Please let us know after the Repair Install. It may, in the end, be better long term to back up and reinstall. If you do this, consider upgrading to Windows 10 after the fresh install.
