DotNetNuke Configuration Error

Object reference not set to an instance of an object.

DotNetNuke has extensive file upload capabilities for content, modules, and skins. These features require custom security settings so that the application is able to create and remove files in your website.

Using Windows Explorer, browse to the root folder of the website ( C:\DotNetNuke by default ). Right-click the folder and select Sharing and Security from the popup menu ( please note that if you are using Windows XP you may need to Enable Simple File Sharing before these options are displayed ). Select the Security tab. Add the appropriate User Account and set the Permissions.

If using Windows 2003 - IIS6
- the NT AUTHORITY\NETWORK SERVICE User Account must have Read, Write, and Change Control of the virtual root of your website

I got the above error when trying to run DNN on a fresh install. I have win2003 and IIS6. I have triple checked the permissions, and the "Network Service" account has 'god' permission on the folders containing DNN.

I'm not sure why the error message says that the root folder of the website is "C:\DotNetNuke by default". I certainly hope it isn't, and I know I didn't install it there. It is in a subfolder of a test website on a different drive entirely.

I believe I have made all the suggested changes to the web.config file, the SQL should be set up properly, and I've copied siteurls.config. What the heck am I missing?

 

I am running IIS 6.0 on Server 2003sp1 with SQL server 2000sp4.

I have enabled Modify for the entire folder tree of my site, the DNN_2 folder sits outside the the default html folder and is a virtual directory as recommended in the install docs. Both the Root\DNN_2 and Root\html folders have NETWORK SERVICE security settings with Modify applied. And I verified in IIS manager that the ASP2.0 web pool has NETWORK SERIVE as security account on the identity tab.

I am still seeing the same error, is it possible another user needs access?

While attempting to test different users, I granted access to the Guests group, which simply gave me an different (more specific) error that it could not access web.config. I also tried granting access to the IIS_WPG group, but no luck.
