win server 2008 r2 iis+php 500 error internal server error.

I encountered an error today, which was an iis 500 error. Because someone else is responsible for the server, and there was nothing unusual when checking the logs. I found that there was no record for a period of time in the task log. I didn’t know why at first, but then everything in the log was 500 error. When configuring the log in iis, I found an error "Unable to use the virtual directory password as the user administrator". Log in to C:cish locally, and finally asked the other computer room staff. The server password was changed, and Restarting the server caused problems with access permissions

After searching on the Internet, a blogger mentioned that he changed the password in the past few days and then reconfigured it, so I followed this idea , start processing it,

1. Go to any inaccessible site in iis7-Basic Settings-Test Settings, and sure enough, both 'Authentication' and 'Authorization' are shown as invalid,

Then you see a 'Link to' button in front of the 'Test Settings' button. Key: Re-type the new password in the settings button behind the specific user column to solve the problem.

But I also found that some sites on the server will not cause errors even if the password is changed, so I checked Baidu, and some comrades said, don’t set it, specific user,

Instead, choose the application below. It may be possible, but since the other party is offline and shut down, it is impossible to check whether it is correct. Make a mark here,
