In the past two days, I received a notification that one of the company's websites cannot be accessed. After accessing it, I found that the page prompted the following error. In the past two days, I received a notification that one of the company's websites could not be accessed. After accessing, I found that the page prompted the following error:
Copy the code code as follows:
msxml3.dll error '80072ee7'
The server name or address could not be resolved
It seems that the prompt indicates that the domain name or address cannot be resolved. Baidu will tell you how to add resolution or DNS settings in the hosts file. From my actual situation, this is not a problem, because the server where this website is located has never been able to access the external network. It can be accessed normally, but it has been inaccessible for the past two days. After checking the prompt file, I found that the file is the global.asa file, and the modification time was in the last two days, and we have not updated the website. So, the first thought is whether it is a Trojan horse? . Then I checked the content of the file and found that an unknown URL was accessed. I initially concluded that the problem should be here. I renamed the global.asa file and then restarted the website. The website access was ok!
So it is basically confirmed that the website is infected by a Trojan horse. Fortunately, the server cannot access the Internet. Otherwise, we don’t know what the consequences will be. Find and fix the loopholes quickly!
