Its IIS v6.0.

Just read over that ticket and the uploads aren't failing. They're being 
added to the library without issue. The issue happens after you close 
the thickbox window and then re-open it. The $_REQUEST (actually $_GET) 
array isn't being set properly and is missing some entries which then 
causes the gallery tab to disapear. Coincidentally, it also happens when 
you load that page outside the thickbox window.
