I have many Windows XP machines running Chrome and Chrome Remote Desktop, and out of the blue they have stopped connecting to my network. Any connectivity that they handled fine 3 days ago, has just simply... vanished. All of them return the same error: Unable to Connect to the Internet (or in Internet Explorer they return "Address not Valid") Pinging the machines returns 50% of the time "Destination Host Unreachable" and "Request timed out." Is anyone else experiencing this issue or is it just my group of machines?
