configuration Error:<authentication mode="windows"/>

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Source Error:

What caused the error?Kindly help me out a solution for this....

WE TRIED OUT THE FOLLOWING...EVEN THAT DIDN'T WORK

Go to the control panel, to the IIS panel on the Web Server and open the default Web Site, find the folder for your application, right click it, choose properties and then in the screen that opens up, hit CREATE (a button). OK your changes and try again.

 

This error occurs because the folder where the .NET application has not been specified as being a .NET application. From the red text above it seems that you have tried to do this but please double check (Google for "creating .NET application IIS" or something similar.

 

Are you using virtual directories? If you are, delete them and add them again. Definitely sounds like a windows authentication problem, obviously...check your permissions, as well.
