After restarting the server IIS service, I found that all ASP pages display http500 errors. In IIS, when the application process protection is set to low, the website asp program can run normally, but when the application process protection is set to medium and high, the asp program displays http500 errors.
Looking for solutions online, it was said that it was caused by the IWAM user password being out of sync. However, when looking at the log file, I found that the description recorded in the log is different from that of the IWAM user password being out of sync. The specific log is as follows:
