Hi,
Thank you for posting your query in Microsoft Community.
As per the description, whenever you try to access websites ends with ".org" you receive error message saying “The parameter is incorrect 0x80070057”. However, the information you provided seems to be incorrect because web browser does not display such error message if unable to access any webpage.
To help you suggest steps to resolve the issue, I would appreciate if you could answer the following questions:
1. Which web browser are you using?
2. Have you made any changes on the computer prior to the issue?
However, if you are using Internet Explorer as your web browser and unable to access websites ends with ".org" then you may follow steps from the article mentioned below and check if that works.
