NCSI is mainly responsible for detecting the Internet connectivity status in addition to is component of NlaSvc (Network Location Awareness service). One of its tasks is to perform a background testing to create upwards one's heed if the auto has Internet connectivity or not. Here, Network location awareness or NLA plant inward coordination alongside NCSI. NLA determines if the network connexion is inward a domain or populace network to define a proper firewall profile.
The NCSI constantly reverts to the changes inward the network conditions. It likewise examines the status of a network connexion inward many ways.
To empathize why pop-ups are happening the article below is structured into below 3 parts, it is imperative that you lot become through all of them-
- How NCSI Functions
- Why at that spot were no windows pop-ups alongside Windows vii in addition to below
- Why windows pop-ups alongside Windows 8 in addition to above
How NCSI functions
- The starting fourth dimension matter NCSI does whenever a network configuration lawsuit or whatever changes inward network configuration occur is that it performs several tests to position the network’s connectivity status. It tries to accomplish http://www.msftncsi.com, a uncomplicated Web site that exists solely to back upwards the functionality of NCSI.
- NCSI performs DNS inquiry for www.msftncsi.com. Next, HTTP contacts the website http://www.msftncsi.com/ncsi.txt. The asking is sent via a patently text file alongside solely content equally “Microsoft NCSI”, thence safeguarding the privacy of user’s information. Then, NCSI performs a DNS inquiry for dns.msftncsi.com.
- This entire procedure runs inward an active mode. However, when other programs create Internet traffic, NCSI turns to the passive monitoring procedure in addition to kicking the bucket along to position whatever alter inward the network status. While performing these tasks, NCSI downloads a text file from the Windows site. Like for Windows 8.1 in addition to before versions, it is http://www.msftncsi.com/ncsi.txt website. And for Windows 10 it is http://www.msftconnecttest.com/connecttest.txt
NCSI in addition to Internet Explorer in addition to Edge popup
You may live on wondering how NCSI affects the pop-up window procedure in Internet Explorer or Edge.
The argue for this pop-up is that the NCSI sometimes cannot contact the website due to or so infrastructure limitations. Therefore, NCSI performs or so passive probe processes. It determines if the organisation has cyberspace access due to the network usage.

When you lot switch “ON” your machine, at that spot volition live on a Yellow Bang grade inward your NIC in addition to a “No internet” connectivity message when you lot cheque your NIC.

The argue for this is the proxy connexion at the office, in addition to Windows non existence able to contact the NCSI website directly.
In such cases, the proxy volition live on contacted inward the background and, usually, the proxy volition require authentication, in addition to afterward it is authenticated, it volition mail you lot to http://www.msftconnecttest.com/redirect. This URI volition redirect you lot to the MSN Portal. It’s a hotspot-like behavior. Hence, this is why you lot teach a pop-up.
How to halt the pop-ups
It has been observed that Antivirus in addition to third-party firewalls may fifty-fifty block the URL– http://www.msftncsi.com/ncsi.txt leading to express access status inward the taskbar inward spite of Internet connexion may fifty-fifty convey issues. These issues tin privy live on resolved yesteryear merely adding “*.msftncsi.com” to the listing of trusted URLs.
