I'm unable to figure out why this one computer on a network cannot resolve URLs. When an address is typed in, the message "Page cannot be displayed" is shown. When the IP is typed in, the page loads. Google was used as a test site.
- The computer obtains a valid IP through the server.
- The computer obtains a valid DNS through the server.
- There is no proxy.
- There are no erroneous HOST file entries.
- Windows Firewall is off and no other firewall programs are loaded
- Cannot ping sites with URL. (i.e. www.google.com receives "Ping request cannot find host www.google.com")
- Can ping site if IP is used instead of URL. (i.e. 74.125.224.48 "Ping replies received")
- DNS service on workstation was stopped and started.
- Computer was rebooted as well as cold booted.
- Changing the DNS manually to different servers did not fix. (8.8.8.8; 208.67.222.222; 208.67.220.220; internal DNS)
- IPCONFIG /flushdns after each DNS change did not fix.
- IE, Firefox, Chrome are all affected.
- No malware detected on full scan using AVG, Malwarebytes and SuperAntiSpyware.
- Checked for rootkit with TDSSKiller and none detected.
- Server is able to browse without issue.
- Other computers on network can browse without issue.
Any suggestions for what to try next or ideas about what is possibly going on would be appreciated.
