 * Installed Vista Business a week ago. PHP+MySQL configured OK. WP runs almost 
   fine except one thing:
 * When I am trying to upload an image (in the Writing a post section), I get the
   following error:
 * **Failed to write to disk. **
 * I have checked the upload directory (default one). It (and its sub-dir) had Full
   Control granted to “Everyone” and I also granted Full Control to “IUSR_xxxx” 
   which is the Internet guest account.
 * Still does not work.

 * I have the same problem.
 * did you ever find a solution?
 * Originally i installed and ran wp on apache on vista business. worked fine including
   upload of images. Long story short, moved wp over to iis7. seemed to work until
   I tried to upload an image. same error message “Failed to write to disk.”
 * Not sure why this is not a support topic. My dev machined is vista. I need to
   upload images to test. IIS permissions seem fine, but who knows. Also I can find
   no trace of an error outside of the message displayed.

 * I have just found the solution to this problem after spending hours trawling 
   the net so I hope this helps you.
 * make a blank file called test.php and just put the following code into it
 * <?php phpinfo(); ?>
 * Now check to see where your upload_tmp_dir is pointing to. I had the problem 
   of it saying not defined. So I created one in the C:/intepub/wwwroot called uploads
   and then opened my php.ini file and changed the following line
 * upload_tmp_dir = “C:\Inetpub\wwwroot\uploads”
 * *remember to uncomment it
 * Then apply the permissions to full in the security tab. Since then it has worked
   fine

 * here’s a wrinkle… i did that but this is what i found:
 * upload_tmp_dir no value no value
 * any idea how to overcome this?
