To allow users to upload profile photographs & images within posts you'll need to configure permissions on your "Uploads" folder within the root of the InstantForum web application
You will need to ensure the MACHINENAME/ASPNET (For Windows 2000 or XP Professional) or the MACHINENAME/NETWORKSERVICE (For Windows Server 2003, 2008, Vista, Windows 7) has "write" permission to both the "Uploads" folder within the forum root.
To ensure administrators can modify skin controls within the Admin CP you will also want to ensure you set "write" & "modify" permissions for the "Skins" folder within the root of the InstantForumweb application.
Identify The Windows Account
We first need to identify which windows account we need to grant modify & write permissions for. To identify which windows account we'll need to add you should first open IIS and click "Application Pools".
Locate the application pool used for your installation and right click to show the context menu. Select Advanced Settings as shown below...
The windows account under which your application pool runs can be seen within the "Identity" as shown below...
In this example the built in system account "NetworkService" is being used for our "DefaultAppPool" which is the application pool used by our InstantForum installation so we'll need to grant the windows "NetworkService" user "wite" & "modify" permissions on the InstantForum uploads folder as discussed further below.
Configure Upload Folder Permissions
You'll need to navigate to your InstantForum installation folder and locate the "Uploads" folder...
From the properties dialog locate the "Security" tab and ensure the windows account listed above has the correct permissions as shown below...
Add the NetworkService account and ensure the NetworkService has "Write" and "Modify" permissions on the "Uploads" folder as highlighted below...
Note: If your application pool is running under the "ApplicationPoolIdentitiy" windows account within IIS you will need to ensure the IIS_Users group has "Write" and "Modify" access on the "Uploads" folder.
Configure Skins Folder Permissions
To ensure administrators can update skin controls from within the Admin CP you'll need to set the same permissions on the "skins" folder...
Again ensure the correct windows account has the correct permissions from within the Security tab within the folder properties.
If you've configured IIS to use an alternative windows account for your application pool you'll need to ensure your custom windows account also has "Write" & "Modify" permissions on the "Uploads" & "Skins
The "Uploads" & "Skins
" folders contains a number of child folders. You should ensure the permissions are propagated to these folders also when applying these changes.
