Detailed introduction: 1. Check the integrity of system files, run system file checking tools, check the integrity of system files, etc.

IIS failure to start may have multiple causes, and the solution will vary depending on the situation. The following are some possible solutions:

1. Check the integrity of the system files: Run the system file checking tool (such as sfc /scannow) to check the integrity of the system files. If any files are damaged or missing, they can be repaired from the Windows installation disk or recovery center.

2. Check port occupancy: Use tools such as netstat to check whether the port is occupied by other processes. If the port is occupied, you can find and end the process occupying the port, or change the port number in the IIS configuration.

3. Start related services: Confirm whether IIS-related services (such as World Wide Web Publishing Service, Internet Information Services (IIS) Manager, etc.) have been started. If they don't start, you can try starting them manually.

4. Reinstall IIS: If none of the above methods can solve the problem, you can try to reinstall IIS. In Add or Remove Programs in Control Panel, select Add/Remove Windows Components and select the Internet Information Services (IIS) checkbox. Then follow the prompts to install.

5. Reset the Windows system: If the problem persists, you can consider resetting the Windows system. In Control Panel, select System and Security->System->Advanced system settings->Startup and Recovery->Settings, and then select Full Restart.

6. Check the metabase file: If the metabase file (such as Metabase.bin) is damaged or lost, you can try the following methods to repair it: copy the temporary backup file (Metabase.bak or Metabase .bin.bak) to Metabase.bin; or rename the corrupted metabase file with a new name (such as Metabase.bad). Then restart the computer.

7. Check file permissions: Ensure that the permissions of all files and folders required by IIS are set correctly. For example, make sure that the application pool's authentication service (such as ASP.NET) has read and write permissions to the required files.

8. Update the operating system and applications: Regularly update the operating system and applications to ensure they are compatible with the latest security patches and updates. Find and install the latest updates on Microsoft's support site.

9. Avoid installing too many unnecessary software: Installing too many unnecessary software may cause competition for system resources, thus affecting the startup of IIS. It is recommended to install only necessary software and regularly clean out programs that are no longer used.

10. Back up important data regularly: Before trying any repair steps, it is recommended to back up all important data to prevent accidental data loss. You can use Windows' built-in backup tools or other third-party backup software for backup.

In short, solving the problem that IIS cannot start requires troubleshooting and repair from multiple aspects. You can try the methods provided above according to the specific situation, and pay attention to maintaining the stability of the system and software during daily use to prevent the occurrence of such problems. If the problem cannot be solved, it is recommended to seek professional technical support help.
