Over the last 3 weeks I have noticed 5 PC's with unexplained DNS connection issues. (2 on workshop bench at present)
You can do all the flushing of DNS etc etc, virus scans etc, manual ip configs, new network cards, but the PC will just not connect to the internet.
Previously I would only see 1 of these "unexplained" in a year.
I've tried blaming MS updates, add on toolbars, firewall triggers any dodgy looking programs.

Reinstall appears to be the only option after trying a failed restore. And I've spent days on looking at and implementing fixes. So after 10 mins of quick tests I go for the restore button and work it from there.

Please download FarbarServiceScanner and run it on the computer with the issue.


Make sure the following options are checked:
Internet Services
Windows Firewall
System Restore
Security Center/Action Center
Windows Update

Press "Scan".
It will create a log (FSS.txt) in the same directory the tool is run.
Please copy and paste the log to your reply.

Please download MINITOOLBOX and run it.

Checkmark following boxes:


Report IE Proxy Settings
Report FF Proxy Settings
List content of Hosts
List IP configuration
List Winsock Entries
List last 10 Event Viewer log
List Installed Programs
List Users, Partitions and Memory size
List Devices (problems only)



Click Go and post the result.
