I was able to successfully install DNN 4.7 in a Windows Hosting plan at Lunarpages.com. Judging from comments in the Lunarpages forum, DNN installs (other than the automatic install of the 4.3.x version to a subfolder) have been a real problem with little or no success.
The key is to work with Tech Support to set read, write, modify permissions for the ASP.Net worker process on the root httpdocs folder. It did take 3 tries to get this permission set to "stick". The first time I apparently reset the permissions when I edited the domain preferences to move the Default.aspx to first place in the default page list. The second time, it apparently reset when I FPT's the DNN files into the httpdocs directory and did not propagate to the newly added folders and files. Finally (before triggering the install), it was necessary to again contact support to reapply the permissions and propagate them to the newly added folders and files.
The database connection string was not a problem but took some searching through Plesk and their web based SQL server management tool (MyLittleAdmin) to find the SQL server name/IP address. While I would feel better being able to directly access the DB using SQL Server Management Studio, their web based tool is not bad.
It took some 4 tries to navigate to /Install/install.aspx before the install could be triggered - each of the earlier tries timed out with Http 404 errors. When the install finally ran, there were no errors and the site came up (using a temporary url) when I clicked to view the newly created portal.
I did run into problems with the temporary url which contained $sitepreview not being properly processed as the Portal Alias so was not able to navigate or successfully click on any link buttons such as Login. See my other thread about this if interested. When I was later able to navigate to the site using the actual rather than temporary url all was fine.
Although Lunarpages does not yet support MS ASP.Net AJAX 1.1 or ASP.Net beyond v 2.0, AJAX seems to work fine since the System.Web.Extensions.dll is intalled in the \bin as part of DNN. It appears that Lunarpages have no current plans to support ASP.Net 3.0 or 3.5. For this reason alone I would not by my own choice pick them but this will not be a problem for this site.
Responsiveness of the site seems more sluggish than other similarly priced plans of shared hosting providers onto which I've installed DNN portals.
