Setting Up Folder Permissions in Internet Information Services (IIS)

This article explains how to set up write permissions in the required folders for configuring IIS for KBPublisher.

Change rights for TEMP directory

PHP uploads get written to windows TEMP directory, and then MOVED to destination directory, and in some cases permissions are not correct. Change windows temp directory to give IUSR 'modify' rights.

Change rights for KBPublisher directories

Using the standard folders structure for IIS and KBPublisher set write permissions for following folders:

• C:/interpub/wwwroot/kb_upload - for uploads via HTML editor
• C:/interpub/kb_file - for uploads via "Files" module
• C:/interpub/kb_cache - for cache files

*Note: this is the default category structure. Your configuration might be different. 

For each of the above folders, do the following:

1. Right-click the directory, then choose Properties
2. Go to the Security tab
3. Find the IUSR account
   (If IUSR is not in the list, add it by clicking Edit, then clicking Add, and then typing "IUSR" in the "Enter the object names to select" field.)
4. Highlight the user in the list, click Edit, and grant the account Modify and Write permissions
