Robert Haken [MVP] napisal(a):
I try to build a simple web aplication in ASP.NET in Visual Studio 5.
When I run finished web aplication from inside VS5:
localhost:1675/test2/Default.aspx
everything is OK, works good.
But when I just navigate in my browser to:
localhost/test2/Default.aspx
i get Configuration Error:
Server Error in '/' Application.
Source Error:
Line 56: <authenticati on mode="Forms"/>
or sometimes:
Line 56: <authenticati on mode="Windows" />
(depends of my blind play with "ASP.NET Configuration")
I'm lame but I just want to made web aplication that may be available
to see
by other people on internet, not only by me :-) I don't want any
authentificatio n.
Help.
Well, you should provide full error description, not only this short
excerpt.
OK:
Server Error in '/' Application.
Configuration Error
Description: An error occurred during the processing of a configuration
file required to service this request. Please review the specific error
details below and modify your configuration file appropriately.
Parser Error Message: It is an error to use a section registered as
allowDefinition ='MachineToAppl ication' beyond application level. This
error can be caused by a virtual directory not being configured as an
application in IIS.

I guess you could have syntax error in web.config file (Parser error?).
If you have really simple application, you don't need the web.config file -
try to rename it to web.config.bak and try the application again.
But if I delete web.config I get other error:
Server Error in '/test' 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.NullRefe renceException: Object reference not
set to an instance of an object.
Source Error:
The source code that generated this unhandled exception can only be
shown when compiled in debug mode. To enable this, please follow one of
the below steps, then request the URL:
1. Add a "Debug=true " directive at the top of the file that generated
the error. Example:
<%@ Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your
application:
<configuratio n>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Note that this second technique will cause all files within a given
application to be compiled in debug mode. The first technique will
cause only that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a
memory/performance overhead. You should make sure that an application
has debugging disabled before deploying into production scenario.
