I am an idiot. The slashes have nothing to do with it. it is the file permissions. I had to update my php.ini file to have the upload_temp_dir point to a temp dir in my wwwroot directory instead of my os default directory. Then I had to grant full control to “Users” and “IIS_IUSR”. Then I had to create an “uploads” directory and again grant full control to “Users” and “IIS_IUSR”. And of course php.ini has safe mode turned off. It works now. I seriously think using windows server 2008 R2 is just way too complicated, I should have used linux, apache, and been done with it.
