Image Upload Problem – IIS 6

Server: IIS 6
WordPress version 3.1.1
Multisite using SubFolders

I’m able to upload images to the server, but thumbnails and full size images do not display. If I try to edit the image, the preview displays. The file exists in blogs.dir. I’m using ISAPI Rewrite to create a httpd.conf file, which contains the block of code listed under Subfolder Example on the Create a Network page in the Codex.

WordPress says the file is here: https://blogs.nvcc.edu/test/files/2011/04/facebook6.jpg.

Actual location is here: https://blogs.nvcc.edu/wp-content/blogs.dir/32/files/2011/04/facebook6.jpg

So many clues… I just can’t put it together.

Any help is greatly appreciated
