Symptom:
When trying to run the cute chat application the following error is generated
in the browser:
Server Application Unavailable
Cause
This is a generic error message. It is displayed as a "polite" error
message to users, hiding the real error details. As such there are a multitude of possible
causes. To remedy the error you must first identify the cause of the
error.
An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Open the Event Viewer and see the error message reported. Please review this log entry to discover what caused this error.
Items to Investigate:
- The default configuration of .NET (certainly for .NET 2) is to
display this error in any client browser that is running on a remote
PC. If you run the browser on the server (or on the PC being used as
a server) then you will normally receive a different error message
that will give you the true cause of the error. That error is the
one you need to address.
- If you still get the error when you run the browser on the
server then check:
- In the Web.config file that "customErrors" has the mode is
set to "RemoteOnly" or "Off". If the mode is set to "On" then
you will only ever see a generic error page and not details of
the error.
- Look in the Windows event log, specifically in the
Application event log. Look at any errors or warnings generated
by ASP.NET. One of these will contain an error dump giving
(some) details of the error.
