Problème de sécurité avec FullTrust

Question

J'ai un assemblage .NET2.0 sur un partage réseau accessible à tous. J'ai activé FullTrust sur la machine de tout le monde pour LocalIntranetZone.

Cependant, sur certaines machines (pas toutes ... c’est la partie qui me rend fou), l’application se bloque. L'erreur que je reçois est ci-dessous.

Je suis complètement perplexe à ce stade. Toute pensée serait grandement appréciée.

Unhandled Exception: System.Security.SecurityException: Request failed.
   at System.Security.CodeAccessSecurityEngine.ThrowSecurityException(Assembly asm, PermissionSet granted, PermissionSet refused, RuntimeMethodHandle rmh, SecurityAction action, Object demand, IPermission permThatFailed)

The type of the first permission that failed was:

The demand was for:
<PermissionSet class="System.Security.PermissionSet"
version="1"

The granted set of the failing assembly was:
<PermissionSet class="System.Security.PermissionSet"
version="1">

</PermissionSet>

The assembly or AppDomain that failed was:

The Zone of the assembly that failed was:
Internet
The Url of the assembly that failed was:
file://xxx.xxx.xxx.xxx/data/Programs/Public/Misc/SomeApp.exe

Answer 1

Le problème est que la zone en échec n'est pas votre LocalIntranetZone, mais bien la zone Internet.

  

La zone de l'assemblage qui a échoué   était: Internet

Si cela ne se produit que sur certains ordinateurs, je vérifierais la topologie de votre réseau car il semblerait que certains de vos ordinateurs tentent d'accéder à l'extérieur de votre intranet lors de l'exécution de votre application.
