I'm trying to install a third DNN 4.6.2 installation on an existing website. We've got two other 4.6.2 installs in virtual directories that have been up and running since sometime last fall on the same website.
I've unzipped the 4.6.2 install and created the virtual directory in IIS (Server 2003 SP1, IIS 6). I've granted permissions for both NETWORK SERVICE and ASPNET to the directory (just to cover all bases).
When I go to the website to START configuration, I get the following error:
DotNetNuke Error: - Version 04.06.02
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Note that this is BEFORE I even get into the installation wizard. When I click on the "Return to Site" link, it takes me to the wizard, but I get three javascript errors (running IE 6) and the page does not have the correct styling, and no images. If I attempt to display any of the images (as http://site/virtualdir/images/rt.gif) I get the same error page as above.
As far as I can tell there are no differences in the configuration or the permissions between this new virtual directory or the other two dnn virtual directories running on the same website.
