&lt;p&gt;Para los colegas que hablan el idioma el problema era:&lt;/p&gt;
&lt;p&gt;S.O. WS2003&lt;/p&gt;
&lt;p&gt;VS 2003&lt;/p&gt;
&lt;p&gt;ASP.NET 1.14xxxx&lt;/p&gt;
&lt;p&gt;A la hora de correr el visual studio y debuggear una aplicacion mandaba un error que decia: &amp;quot;error while trying to run project unable to start debugging on the web server could not start asp .net or ATL server debuggin&amp;quot;&lt;/p&gt;
&lt;p&gt;Bien intente lo siguiente segun lo investigado en muchos foros y soluciones de microsoft:&lt;/p&gt;
&lt;p&gt;* Agregar a los sitios de seguridad en IE el http:\\localhost&lt;/p&gt;
&lt;p&gt;* Cambiar los permisos de seguridad en el IE Automatic logon whit current user name and password&lt;/p&gt;
&lt;p&gt;* Me asegure que estubiera bien seleccionada la version del ASP.NET a la 1.14 en el proyecto dentro del IIS&lt;/p&gt;
&lt;p&gt;* Me asegure que en las propiedades del directorio en el iis en la pesta&amp;#241;a de directorio-&amp;gt;Application settings-&amp;gt; boton de configuracion en la pesta&amp;#241;a de debugging estubieran marcadas las dos checkboxs ahi mismo en la pesta&amp;#241;a mappings en la extension .aspx que estubiera haciendo referencia a la version correcta del ASP.NET y que aparte de eso los verbos incluyeran Debuger.&lt;/p&gt;
&lt;p&gt;* Me asegure que la carpeta de los temporales de la version del ASP.NET tubiera permisos FULL.&lt;/p&gt;
&lt;p&gt;Sin embargo nada de esto solucionaba mi problema hasta cambiar el archivo UrlScan.ini que se encuentra en \System Root\System32\Inetsrv\Urlscan\ en la parte de [AllowVerbs] se tenia que verificar que estubieran estos verbos:&lt;/p&gt;
&lt;p&gt; *GET&lt;/p&gt;
&lt;p&gt; *HEAD&lt;/p&gt;
&lt;p&gt; *POST&lt;/p&gt;
&lt;p&gt; *DEBUG&lt;/p&gt;
&lt;p&gt;Bien cuando yo abri este archivo y ubique [AllowVerbs] no tenia el ultimo verbo DEBUG asi que lo escribi y guarde el archivo y se soluciono el problema.&lt;/p&gt;
&lt;p&gt;La causa imagino es la que menciona Alain es producto de instalar la version de ASP.NET 3.5 &lt;/p&gt;
&lt;p&gt;Saludos y espero sirva esta informacion &lt;/p&gt;
&lt;p&gt;Nota:Por cierto inverti casi una semana encontrando esta solucion pero que bien se siente solucionarlo al fin &lt;/p&gt;
