Hi,

I am trying to do a fresh install of 5.04.02 on 2008r2 server with sql 2008r2

This server & datbase already have a previous version dnn site working fine.

New site is using its own app pool. Ive added the app pool from the web server to full control in file access. The app pool is using ASP.net 4 in integrated mode

error I am getting is

Hi Tango,

Just an idea, but as the stack trace begins in DotNetNuke.Common.Utilities.Config.GetConnectionString have you checked that the <connectionStrings> section of your web.config is setup correctly? If the same server already has a working DNN install then compare the web.configs. Just make sure you don't put both DNN installs into the same database - that's probably not what you want.

Regards,
Rhys

Thanks Rhys,

Is there any changes in the newer versions of DNN. I have always only updated 2 sets of credentials in the web.config.

I have the new version pointing to a new database.

Any other ideas, thanks again

Trap for young players

make sure you move the comment --> from the end of the connection string & in my case added it to the end of the comment (if this makes sense)

<!-- Connection String for SQL Server 2005/2008 -->
    <add name="SiteSqlServer" connectionString="Server=xxxxx;Database=xxxxx;uid=xxxxxx;pwd=xxxxx;" providerName="System.Data.SqlClient" />
    -->

In effect I had the connection string commented out
