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 220.127.116.11 as DNS server, tried Comcast DNS servers, but nslookup works so it isn't the DNS server.
-Inserted an entry in the "hosts" file - 18.104.22.168 google.com (then tried to ping google.com, no luck)
-Uncommented 127.0.0.1 localhost and pinged localhost still get "Ping request could not find localhost".
