Hello,

I have set up DNN 07.00.05 on a MS 2008 server with sql express 2008 and having problems with the site running stable and giving the message that the site is unavailable or under construction default message.

Here is the error i found in the portal log:

the sql server and browser are using local system. Should the interact with desktop be selected? or maybe a domain level admin or system account be used here? any help would be greatly appreicated

Here is the connection string:

<connectionStrings>
    <!-- Connection String for SQL Server 2008/2012 Express -->
    <add name="SiteSqlServer" connectionString="Data Source=.\SQLExpress;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
    <!-- Connection String for SQL Server 2008/2012
    <add name="SiteSqlServer" connectionString="Server=(local);Database=DotNetNuke;uid=;pwd=;" providerName="System.Data.SqlClient" /> 
    -->
  </connectionStrings>
  <appSettings>
    <!-- Connection String for SQL Server 2008/2012 Express - kept for backwards compatability - legacy modules   -->
    <add key="SiteSqlServer" value="Data Source=.\SQLExpress;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True" />
