Problema de seguridad con FullTrust

Question

Tengo un ensamblado .NET2.0 en un recurso compartido de red para que todos puedan acceder. He habilitado FullTrust en la máquina de todos para LocalIntranetZone.

Sin embargo, en ALGUNAS máquinas (no todas ... esa es la parte que me está volviendo loco) la aplicación se bloquea. El error que obtengo está debajo.

Estoy completamente perplejo en este punto. Cualquier idea sería muy apreciada.

Answer 1

El problema es que la zona que falla no es su LocalIntranetZone, es la zona de Internet por alguna razón.

  

La zona de la asamblea que falló   era: Internet

Si solo está sucediendo en algunas computadoras, comprobaría la topología de su red porque parece que algunas de sus computadoras están tratando de llegar fuera de su intranet cuando ejecutan su aplicación.
