Error

Hola gente sabia de estos programas, aqui le pongo el
mio: tengo messenger 6.2 y he tenido problemas para
conectarme, me manda el aviso que no me conecta y le doy
en el de solucionador de problemas y me dice lo siguiente:

Server Error in '/' Application.

Runtime Error
Description: An application error occurred on the server.
The current custom error settings for this application
prevent the details of the application error from being
viewed remotely (for security reasons). It could,
however, be viewed by browsers running on the local
server machine.

Details: To enable the details of this specific error
message to be viewable on remote machines, please create
a <customErrors> tag within a "web.config" configuration
file located in the root directory of the current web
application. This <customErrors> tag should then have
its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>


Notes: The current error page you are seeing can be
replaced by a custom error page by modifying
the "defaultRedirect" attribute of the application's
<customErrors> configuration tag to point to a custom
error page URL.

Espero sus respuestas, y de antemano mil gracias.


<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="RemoteOnly"
defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>
