SharePoint failed to connect to the configuration database error

This error is fixed when sharpoint is installed. Check by msdn and no problem is found. When you reinstall sql2005, you will find that it was an SQL problem. You need to fix WMI and the SQL installation self-check fails. Use the script to fix the issue.
