I have a Windows 8.1 desktop machine (spec below) that has been running fine for over a year.
Over the last couple of months, roughly once a week, my network connections stop working. If I reboot Windows, it all starts working again until next time. Network is physical with static IP. Wireless on same machine also fails when this occurs. Other devices on wireless or physical cable continue to work.
What I see when this happens is:
- The DropBox system tray icon shows there is no connection (i.e no sync or green tick icons)
- No web page will load from any browser. I don't get an error, browser just does nothing, but shows URL in address field
- RDP/SSH to other machines fails. I have a permanent RDP connection open to another local machine that continues to work when the rest of the networking stops. If I close it, it won't reconnect.
I checked the Event Logs, and have found nothing that points to the problem. I have also tried Google and found nothing.
Can't remember what happens if I try to PING an IP locally or remotely. I think it works, but as I am not in front of that machine right now I cannot say for sure. I will update later.
Although the reboots don't take too long, it is becoming annoying to keep having to do this. So I'd like to find a solution...

in a cmd window. If this succeeds, it's probably not DNS.
