The recent Department's web server was suddenly inaccessible!

Overtime work!

Symptoms of the problem:

1. "Internet Explorer cannot display this page"

2, the site configuration is normal, yesterday can also have a good visit

Where exactly is the problem?

By analyzing the HTTPERR.log file, it is found that the display is all "connections_refused".

This may be the key to the problem. As shown in the following:

Microsoft Official website just have the solution: HTTP://SUPPORT.MICROSOFT.COM/KB/934878/ZH-CN

This problem occurs if the available nonpaged pool memory is not sufficient for the 20mb,http.sys service to stop receiving new connections. This also explains why restarting IIS is useless and can only be resolved by restarting the Web server to free up memory resources.
