We have a website previously with a login system with Windows NT authentication. We are changing this to our own login form with custom login information and suchs. Now when we upload an image (which works in both situations) and then try to rename the file we get an error 'Unable to rename the item' (see screenshot). When we were still using Windows NT authentication it worked well, so this is most likely an issue of rights.

 

We have already tried running the website not under the standard IUSR_SERVER user but under a specific user with expliciet modify rights in the upload directory, but this doesn't solve the problem.

 

Does anyone have experience with this and knows how to solve this?

 

With regards,
