Hi

I have two questions:

1 - I want to know if it's possible install DNN on a comercial server that do not offer suport for DNN, the server offer support for ASP.NET 2 and SQL Server Express.

2 - If the question 1 is YES, How can i install it on that server? I only have saw tutorials for installing DNN locally

Thanks in advance

1) yes, though a hosting provider with dedicated DotNetNuke experience and support might be a great advantage

2) please check out the installation guide on Documentation page in Resources menu above. usually you install using a remote console if available.

if the hoster allows to control permissions for the root folder, you can also just copy all files into it. make sure to grant full permission for the account used by ASP.Net to access files.
