Hi I am trying to create another copy of my current DNN 4.5.4 portal website on my XP workstation. I've done the following:
1. copied the website directory, and all the subfolders and files (including .dlls) to a new directory -- preserved the same folder structure.
2. Created a new IIS virtual directory
3. Pointed the new virtual directory to point to the new web folder.
4. Configured the security permissions in the IIS virtual directory to match my old website
5. Added a new entry into PortalAlias to match the new virtual directory URL
My old website works fine but i get the following error when I try to load the new website:
