Installation problem with Log4Net Dashboard 1.2: Object reference not set to an instance of an object.

Dear mailing list,

I'm getting into troubles installing Log4Net Dashboard 1.2 on a Windows 
2003 server that runs IIS 6.0 with .NET v1.1.4322.

After installing the software using the installation files from 
http://www.l4ndash.com/Download/tabid/53/Default.aspx, the URL 
http://localhost/l4ndash returns the following error:

Server Error in '/L4NDash' Application.
--------------------------------------------------------------------------------

Object reference not set to an instance of an object. 
Description: An unhandled exception occurred during the execution of the 
current web request. Please review the stack trace for more information 
about the error and where it originated in the code. 

Exception Details: System.NullReferenceException: Object reference not set 
to an instance of an object.

Source Error: 

An unhandled exception was generated during the execution of the current 
web request. Information regarding the origin and location of the 
exception can be identified using the exception stack trace below. 

Stack Trace: 

[NullReferenceException: Object reference not set to an instance of an 
object.]
   FNFrmw.FNSessionData.GetSession() +22
   L4NDash.State.SessionData.GetSession() +5
   L4NDash.UcFooting.Page_Load(Object sender, EventArgs e) +9
   System.Web.UI.Control.OnLoad(EventArgs e) +67
   System.Web.UI.Control.LoadRecursive() +35
   System.Web.UI.Control.LoadRecursive() +98
   System.Web.UI.Control.LoadRecursive() +98
   System.Web.UI.Page.ProcessRequestMain() +750

--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:1.1.4322.2032; 
ASP.NET Version:1.1.4322.2032 

The error does not seem to be connected to the web.config, as if the same 
error occurs even if web.config is deleted.

Unfortunately, I have no idea why the error occurs, and couldn't find any 
information on this mailling list.

Thank you for your help!

Best wishes,
Christoph

Hi Christoph,
 
Have you checked that the web server (IIS) has session handling enabled?
