Tenemos en una red local una máquina en XP y otra en
Windows 98 que tiene una software en Cobol que ejecutamos
diariamente.
Al ejecutar via red ese programa desde la máquina en
Windows XP siempre nos aparece una ventana de advertencia
que deseamos que no aparezca ya que dicho soft no
contiene ningun tipo de código malicioso.

Concretamente este es el texto que aparece:

...

La opcion última aparece sombreada sin posibilidad de
desactivarla.

¿ Alguien sabe como anular esta protección ?

Gracias por anticipado.
