  1. multiple issues starting with dns and netio.sys in Windows10


    I just got a new Asus laptop with windows 10

    1. I did full updates from Microsoft windows10 updates and later realized maybe I should have updated Asus hardware drivers first. Now I am having BSOD issues & netio.sys errors forcing me to reboot at least twice so far. Since then I’ve not had this issue so far.
    2. I shutdown my laptop everyday. I just noticed from task manager and confirmed in cmd prompt commands my laptop is running for several days. Wondering if this is normal or a setting somewhere or related to issue 1. ?
    3. I was having slow internet issues – rebooted modem , no help. Then I found out I had to flushdns , etc and so far no more issues. Is this also related to issue 1. ?

    Should I do a factory reset ? Everything is up to date and I've scanned for viruses and its clean. Please advice. Thank you

    Hi Rita French,

    This issue often occurs when the DNS settings are incorrect. I suggest you to perform the following methods to troubleshoot the issue.

    Method 1:

    I would recommend you to change the Preferred DNS server and check if it helps.

    • Press Windows + R keys to open Run window, type
      ncpa.cpl and press Enter.
    • Right-click on the connection that you use for the local connection, and then click
    • Click to select Internet Protocol Version 4 (TCP/IPv4), and then click
    • In the Internet Protocol window, let's change the Preferred DNS server to
    • Click OK twice to complete the modification.

    Note: If the issue persists, please repeat the steps and change the "Preferred DNS server" to

    Method 2:

    If that does not help, try to flush the DNS. Follow these steps below.

    • From Start screen, type Command Prompt.
    • Right-click on Command Prompt and choose Run as Administrator.
    • Type: ipconfig /flushdns and press Enter.

    Note: The ipconfig /flushdns command provides you with a means to flush and reset the contents of the DNS client resolver cache. During DNS troubleshooting, if necessary, you can use this procedure to discard negative cache entries from the cache, as well
    as, any other dynamically added entries.

    Hope any of these methods help!

    Kind regards,

    DNS server causing problem

    Hi Andrea,

    DNS is a server that translates websites' addresses so that browsers can connect to them. If the addresses become outdated or the server has issues, problems and DNS errors occur. For us to provide an accurate solution, we would need you to answer the following

    • Which build, version and edition of Windows is installed on your computer?
    • What changes have you made to your device before this issue occurred?
    • Are you experiencing the same issue regardless if you are trying to be connected to a wired or wireless connection?

    For initial troubleshooting, we suggest deleting the DNS cache. This can refresh the DNS files and settings on your PC. Follow these steps to delete the DNS cache:

    • Using Search type Command Prompt.
    • Form the search results, right click on Command Prompt (Desktop app) and then choose Run as administrator.
    • In the Command Prompt window, type ipconfig /flushdns and then hit the Enter key.
    • Once done, restart your computer and then check if the same issue persists.

    We are looking forward to your response.
