I access Visual Studio 2005 application to build my website from a remote system of the company that will host the website. I was building an asp.net website (website name is ThirdApp) following an example in a book. When I tried to run the application, following the exact steps in the book, I get the error below:
Server Error in '/TimeEnd Application. (TimeEnd is my folder on the remote system)
Configuration Error
Description: An error occured 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='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Line 52: <! - -
Line 53 : The <customErrors> section enables configuration
Source File: X:\Websites\TimeEnd\ThirdApp\web.config

After getting this error, I am unable to launch Visual Studio 2005 any more. Each time I attempt to start Visual Studio 2005, I instead get the error I described above.

What is the problem?
