I tried to install DotNetNuke 3.2.2 on a Windows 2003 Server PC, using instructions contained in book entitled "Professional DotNetNuke ASP.NET Portals," and ended up hitting an error (see below). Any ideas as to what could be wrong? One issue that may be related, and I mention it just in case, is the fact that when I went to assign rights to the C:\Websites\DotNetNuke folder, I never saw the user mentioned in the book on page 38. I only had the following choices:

Account Unknown(S-1-5-21- etc.), Administrators (OMEGA2003\Administrators), CREATOR OWNER, Everyone, SYSTEM, Users (OMEGA2003\Users).

I just assigned Full Control rights to Everyone to try to get it to work and got the following error:

Hi guys,

I am getting exactly the same error. In my case however I am using IIS 5 on a XP machine. I have followed the installation guide and believe that the security on the DotNetNuke folder is correctly set.

Resolution to this issue will be highly regarded.

Thanks in advance.
