The SQL Server System Configuration Checker cannot be executed due to WMI configuration on the machine Error:2147749896 (0×80041008).

A couple of days back I  had my computer formatted. I reinstalled it with Vista SP1 32bit. Subsequent to installing other indispensable software  I tried to install SQL Server 2005 .  However, it instantly displayed the following error message.

The SQL Server System Configuration Checker cannot be executed due to WMI configuration on the machine Error:2147749896 (0×80041008).

It was a bit frustrating for me as it was pretty late and I ardently wanted to install SQL Server 2008 right after I was done  with installing SQL Server 2005. I pinged my friend James Locazicoski with the above error message. James came to my rescue with a batch file. I immediately ran the batch file on my server;  it took a while and when it was done it closed itself on vista. I kept my fingers crossed and ran my SQL Server installer right after that.   There was no WMI error to wreck my nerve. I was able to successfully install SQL Server right after that.

Well, this bat file is certainly a life savior. While searching online I found this script at several places, which reflects its popularity and usability. I need help from my readers regarding the following information

1) Where is the original source of this script?

2) What is this script actually doing?

Once I receive response to both the above questions, I will post the answers  on my blog with due credit to my readers.
