What is Msftconnecttest.com?

Msftconnecttest.com is a domain used by the Windows operating system to verify internet connectivity. When a device connects to a network, Windows sends an HTTP request to http://www.msftconnecttest.com/connecttest.txt and expects a response containing the text “Microsoft Connect Test.” If this response is received, the system determines that the internet connection is active. Otherwise, it may consider the connection unavailable or limited.

This process, known as the Network Connectivity Status Indicator (NCSI), helps Windows and applications understand the network’s connectivity status. For example, when connecting to public Wi-Fi networks that require a login via a “Captive Portal,” the request to msftconnecttest.com may redirect to a login page. If this redirection does not occur, users may encounter an error indicating msftconnecttest.com is unreachable.

Issues with accessing msftconnecttest.com can stem from DNS settings, the use of proxy servers, or enabling the DNS over HTTPS (DoH) feature. To troubleshoot, you might temporarily disable DoH in the browser or system settings and check network configurations.
