Problema di sicurezza con FullTrust

Question

Ho un assembly .NET 2.0 su una condivisione di rete a cui tutti possono accedere. Ho abilitato FullTrust sul computer di tutti per LocalIntranetZone.

Tuttavia, su ALCUNE macchine (non tutte ... questa è la parte che mi sta facendo impazzire) l'app si blocca. L'errore che ottengo è di seguito.

Sono completamente perplesso a questo punto. Ogni pensiero sarebbe molto apprezzato.

Unhandled Exception: System.Security.SecurityException: Request failed.

The action that failed was:
LinkDemand
The type of the first permission that failed was:
System.Security.PermissionSet
The demand was for:
<PermissionSet class="System.Security.PermissionSet"
version="1"
Unrestricted="true"/>

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

Il problema è che la zona che non funziona non è la tua LocalIntranetZone, è la zona Internet per qualche motivo.

  

La zona dell'assembly non riuscita   era: Internet

Se succede solo su alcuni computer, verificherei la topologia della tua rete perché sembra che alcuni dei tuoi computer stiano cercando di raggiungere l'esterno della tua intranet quando esegui la tua app.
