When this happened I had no internet access on all four browsers I had open.
Ping Plotter Pro was running with no problems to 4 targets. I had an internet connection. But I could do nothing on any browser.
I had this error one other time two days ago in Event Viewer while I was asleep but Fx and Opera were running on the taskbar.
I rebooted and everything seems ok. There is nothing in Action Center. Before I rebooted, I used the internet connection troubleshooter and it detected no problems yet I could not use my browsers at all to surf until I rebooted.
Since this has happened twice in two days, it may happen again. How do I troubleshoot it? I didn't think to use CMD and netstat -n or netstat -b to see what application is using so many ports. If I had seen a particular application using all the ports and I closed it would that have avoided having to reboot?
