Provide (Set) Read Write permissions to folder (directory) in IIS

Hi indradeo,

• Right-click the directory, then choose Properties. Go to the Security tab.
• Find the IIS_USR account (If IUSR is not in the list, add it by clicking Edit, then clicking Add and then typing IIS_USR in the Enter the object names to select field).
• Select the user from the list. Click Edit and check the checkbox to set Modify and Write permissions. Then Apply.

Repeat the steps for NETWORK SERVICE and IIS_USRS account.
