Hi,

I am trying to publish a website, but i can't get the aspx file to load
instead i get the above error and the following stack trace:

[NullReferenceException: Object reference not set to an instance of an
object.]
   System.Web.Hosting.ISAPIWorkerRequestInProc.GetServerVariable(String
name) +1618
   System.Web.Security.WindowsAuthenticationModule.OnEnter(Object
source, EventArgs eventArgs) +593

System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
+92
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&
completedSynchronously) +64

I am using asp.net v2.0, VS2005 & IIS 5.1 (configured to run asp.net
2.0).

..htm and .asp files load ok. The problem seems only to be with .aspx
files. I gather this may be a framework problem. But I have no idea how
to fix it. Any ideas?

Thanks.

After many high speed collisions between my head and a brick wall, all
i needed to do was register the ASP.NET extensions in IIS, as i had
installed IIS after the .NET framework. Simply go to command window and
run aspnet_regiis -i (The -i option installs the needed associations in
IIS) in the WINDOWS\Microsoft.NET\Framework\vX.X.XXXX directory.

I hope this may help someone. :)
