Salve raga!!
Sono un neofita dei servizi web...
ho questo problema:
sul mio solito server di sviluppo ho installato il framework 2.0 e gira e i siti vanno ecc..
allora ho provato a creare un web service, tanto per intenderci ho compilato il progetto che VS2005 mi ha creato. a questo punto ho un web service che si trova in un url del tipo: http://192.168.2.254/WebService/WebService.asmx

Quando però cerco di interrogarlo tramite un PC della rete tramite un'applicazione Windows .NET Frmwrk 2.0 (in vb) mi da il seguente errore:

System.Security.SecurityException was unhandled
