I need to create a subfolder that the app pool can read and write to for my my search index files. How can I create an empty subfolder and grant access to my app pool process? Thanks.
The application pool of your site has read and write permissions on your root and all subsequent directories by default. You just need to create a subfolder using your favorite ftp client. All permissions will be inherited from the parent folder.
I still get E:\web\***\lucene_index\write.lock' is denied. I created the DIR with FTP, but the process will not let me write files to it. Thanks.
Also, you can misconfigure your ACL permissions when you used web deploy. Please read our knowledge base article and our blog post article on how to prevent this from happening again. Contact our support department and ask them to reset the ACL permissions for your hosting account.
