Hi I've used DNN 4.9 on SQL 2000 and Server 2000 and IIS5 with very few issues 

Now I'm upgrading to running on Server 2003 with SQL 2008 and IIS6

I Installed SQL 2008 together with framework 2,3,3.5 as required from slq 2008.

In IIS6 I set as framework 2.0.50727

Installed DotNetNuke_04.09.00_Install after configuring web.config to run with SQL 2008.

Installation worked okay, added a Skin and it locked up.

On reboot the response is now always 

Compiler Error Message: BC30451: Name 'Config' is not declared.

Source Error:

Line 66:         Private Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
Line 67: 
Line 68:             If Config.GetSetting("ServerName") = "" Then
Line 69:                 ServerName = Server.MachineName
Line 70:             Else

Replaced the Web.config with default.config ...still same message.

Ran asp_net regiis-i as forum suggested ....still the same message.

removed all files and re-installed completely set up IIS again ....still the same message.

What else can I do to fix this anyone?

In  a virtual directory. 

Since I posted this I have also followed the same process and installed on another server albeit using iis5 and server 2000 and pointed to a sql 2000 database and it is working fine.

What area of the config file should I look at?
