Application pool automatically stops problem solving and IIS 7.x 503 error solving

A netizen said that IIS 7.5 always reports a 503 error. The author gave it a remote connection and began to suspect that it was a problem with IIS settings. For example, the. NET version and application of the application poolProgramThe version is inconsistent, or there is a problem with the website binding. Find the correct reason. Think of a try. in the case of Net, a static html file is created, which is put into the IIS website. If you browse this HTML file, the error 503 is still reported, it is found that the application pool corresponding to this website is automatically stopped after receiving the HTTP request. This is true after several attempts. I found it online, some people said they want to change the application pool identity (http://www.iisboy.com/iis_article/398.html), such as LocalService, LocalSystem, networkservice, applicationpoolidentity, the Administrator account of the local machine, etc, after trying several accounts, I still couldn't do it. So I continued to find the answer and began to suspect that there was a problem with this IIS installation. Later, I found a person with the same problem. I made an HTML file and still couldn't solve the problem. But after this guy tried to install the HTTP redirection feature, the application pool automatically stops. But the problem is not over yet. When you access this HTML, the error 503 is returned. This problem is complicated. I think its IIS has been broken. We recommend that you reinstall Windows 7. The netizen took care of the problem and solved it. Later I thought about other methods, such as troubleshooting HTTP. sys, but that would be complicated. The method for reinstalling the system is the simplest among these methods. The problem is solved.

Hope to help you!
