Here is a solution for self hosting iis users using fastcgi with php.

First make sure you have the uploads folder in your wp-content folder.
Second add the user everyone to the folder wp-content with modify permissions. Restart iis and test image upload in WordPress.

If it works your on the right path here.
Now remove the everyone user and add the NETWORK SERVICE user to this folder.

But wait! I do not know how to add the everyone user or the NETWORK SERVICE user to my wp-content folder?

Browse to the folder and right click on it.
Select the properties option.
Now select the security tab at the top.
Click the edit button.
Click the add button.
In the select users or groups text field enter in:
NETWORK SERVICE
click the ok button.
In the section Allow: check the modify box.
Click the ok button.
It will run for a bit then click the ok button
on the property window and your done.

I used the everyone user to check if this issue was a folder permissions issue only. Then used the NETWORK SERVICE user based on fastcgi set up information. depending on your set up with fastcgi it could be a different user so you will need to start testing users to find the right user you need.

It seems logical that this could be the same issue others are having with themes updates and plugins as well. I am not sure if the NETWORK SERVICE user needs permissions over all of the wp-content folder yet it seems like it is needed.

I hope this helps some of you WP users out there as it took me a few nights to figure this one out.

I would also like to say thank you to all the users who report back full solutions to issues they have found closing the loops and ending the searches.

We need more of you. ??
