If the service account has already been added as an administrator on the server, and the issue persists, you may want to consider the following additional steps:
Check Sitecomp.log for Additional Information: Review the Sitecomp.log file for additional details on the error. Look for any other error messages or warnings that might provide more context.
Review SMS_EXECUTIVE Log: Since SMS_EXECUTIVE service is not found in services, check the SMS_EXECUTIVE log for any errors or issues during its startup. This log is crucial for understanding what might be causing the failure.
Review Windows Event Viewer: Check the Windows Event Viewer for any relevant error messages or events related to the SMS_SERVER_BOOTSTRAP service. This might provide more detailed information about the cause of the issue.
Ensure Dependencies are Met: Ensure that all dependencies for the SMS_SERVER_BOOTSTRAP service are met. This includes checking that necessary services and components required for SMS are installed and running.
Overlapped I/O Operation Issue: The error message specifically mentions "Overlapped I/O operation is in progress." This could be related to conflicts with other I/O operations. Check if there are any third-party applications or antivirus software that might interfere with the installation.
Firewall and Antivirus: Confirm that firewall and antivirus settings are not blocking any essential communication between the site server and the management point.
Reboot: Sometimes, a simple reboot of the server can resolve certain issues. If possible, try restarting the server and then reattempt the installation.
Check Site Status: Verify the overall health and status of your Configuration Manager site. Use the Configuration Manager console to check for any site-related issues or warnings.
