Hi,

I am trying to install DotNetNuke 5.3.1, but get an error message when opening the default.aspx webpage. I am using a Windows XP system, SQLExpress and IIS 5.1. Because using XP, I have the user ASP.NET granted “Full Control” on the “C:\DotNetNuke” directory and made this user db_owner of the DotNetNuke database. (Because trying to solve the problem, I also granted the NETWORK SERVICE account full control on the DotNetNuke directory and made this also db_owner).

In the web.config file, the connection string I have set as: connectionString="Data Source=VIDEO\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=C:\DotNetNuke\App_Data\Database.mdf;"

Can anyone tell me why I got this error message, opening the default.aspx webpage?

Thanks in advance!

Hi Mitchell,

Thanks for your reply! Can I, form your reply, conclude that if I use SQLExpress and database.mdf with the connectionstring I am using and earlier mentioned, I do not have to define a database in SQLExpress and the database will be generated in SQLExpress through the installation scripts? In any case, I will try.

SQLExpress with user and password and the right connection string I already tried in an earlier stadium, but does'nt work in SQLExpress.

Sincerely

Lef
