    After updating to 8.1, inbound/outbound traffic blocked


    Hello.

    I was running Windows 8 x64 without any issues. Recently I updated to 8.1 and am having a weird issue.

    The internet works fine for general browsing and even for streaming like netflix or pandora/spotify. However, when I am using a program other than a web browser that pulls information in from a server based on data that I enter, it seems like it isn't going through. It is like the program doesn't even see the internet.

    I am a pilot and have a program that allows me to input data and retrieve charts and other pertinent information for my proposed route. When I enter in the data and press the button to retrieve the charts, etc, I get a message saying error downloading files. At first I thought it was this program or a problem with their server. However, over the past days every program that I use that pulls information from the internet is doing the same thing more or less. I have weather planning programs that can't get map or weather data; I have flight and rout planning programs that can't even retrieve the listing of airports, and I have performance calculators that will not receive any information. These are just some of the programs that I use. They are all made by different developers and connect to different servers. I can't even get a basic application to receive NOAA weather data.

    I tried adding a firewall rule for the applications and when that didn't work, I disabled the firewall all together through the advanced settings. I also disabled windows defender. There is no other AV program running on my machine at the moment and it still will not connect. Then again, oddly enough, I can use the internet fine from a browser. Can anyone think of what this may be? There have been no changes other than 8.1 being loaded.

    Thanks in advance.

    I just found a more relatable example of when this is noticed. I was trying to add a local USB printer through the Windows Add Printer dialog. When I click the button to update the list of printers, I get a message saying: "Unexpected error occurred when downloading printer list. Check your connection."

    Damn man, a pilot? Rather cool if you ask me. In another life, perhaps I will be one too.

    Check Internet Explorer (desktop version). Open it then click the gear-looking icon in the top right, then choose Internet Options.

    Go to Connections tab and click on LAN Settings.

    Uncheck all boxes there then click OK 2x, then close IE.

    Try your programs again, to see if they communicate well.

    Thanks! There's really a need for good pilots right now and even more within a few years. If it interests you...check it out at your local airport. Most have places where you can get lessons. It isn't as unattainable as most people think.

    On topic, unfortunately the boxes were already unchecked. I also have no third party security installed, only Windows Firewall/Defender, both of which have been disabled.

    It could be that the actual programs that are not communicating well have their own proxy settings set unwell. So, check that.

    Other things to try:

    1) Update wireless and/or wired drivers from manufacturers' websites.

    2) Set your router's DNS server to any one of the OpenDNS addresses.

    3) Update router's firmware to latest. (Probably won't help, but excellent practice to do so.)

    If those don't work out for you, please open an elevated command prompt and run this command:

    ipconfig /all

    Then take screenshot of it with snippingtool.exe and post results here.

    I made sure all drivers were up to date already, as well as updated router firmware. I also installed a spare router from a completely different manufacturer yesterday as a test. (Linksys vs Motorola). Both are fairly new with N and AC bands.

    I switched from my ISPs DNS servers to openDNS servers. I tried again, but still no dice. The programs to not have any networking or proxy settings. I am not running through VPN or proxy. Like I said, even windows update can't connect. Yet I am writing this on the forums from the same machine. Here is the results of an ipconfig and ping to google just to show connectivity.

    Everything looks alright. Truly a weird situation.

    Check C:\Windows\System32\drivers\etc\hosts with Notepad to ensure there are no weird entries there.

    In worst case scenario, perhaps running the tool in Brink's thread here and posting the results will help us determine what it is on your system that is causing issues.

    In the meantime and in between time, it can not possibly hurt if you run Ccleaner to clean the machine of all junk files, then running its registry cleaner too. You can check the box for DNS Cache (under "System" on Windows tab, before running.) (The reg cleaner is excellent and will never hurt Windows' operation.)
