DNN works when going to http://03a78f9.netsolhost.com/home/.
In the home directory there is a web.config file with the following references to 03a78f9:
<connectionStrings>
<!-- Connection String for SQL Server 2008/2012 Express -->
<add name="SiteSqlServer" connectionString="Server=ATL4WDPSQL01I2;Database=3_03a78f9_0;uid=3_03a78f9_0;pwd=w3HqeFZf5p;" 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="Server=ATL4WDPSQL01I2;Database=3_03a78f9_0;uid=3_03a78f9_0;pwd=w3HqeFZf5p;" /> <!-- Connection String for SQL Server 2008/2012 - kept for backwards compatability - legacy modules
<add key="SiteSqlServer" value="Server=(local);Database=DotNetNuke;uid=;pwd=;"/> -->
Should any of these "03a78f9" be changed to "fencer"?
