Hi,
Problem I have is that ckfinder wont allow me to delete or rename the file unless the "Customer Sites" is also an owner with Full Control of the new file
So do you mean that after file upload, you want rename the file on the server? Or rename it in web application?
If want rename it on the server, I think the issue is you may not grant IIS_IUSRS full permission.
To grant IIS_IUSRS permission and understanding Built-In User and Group Accounts in IIS 7, refer:
