Sto lavorando su un sito Web ASP.NET che chiama un database DB2. Ho installato Visual Studio su un server Windows 2008 in cui verrà ospitato il sito. Quando eseguo il debug del sito in Visual Studio, utilizzando il server Web integrato, posso connettermi al database e il sito funziona correttamente. Quando imposto il sito su IIS7, sullo stesso server, non riesco ad accedere al sito o al database a causa del seguente errore.ASP.NET - IIS7 - IBM DB2 Edizione
Ecco i dettagli tecnici:
Windows 2008 Server
IIS 7
Visual Studio 2010 Premium
DB2 v9.5.301.436

Non capisco come il sito può funzionare bene utilizzando il server Web Studio visiva e non lavorare in IIS. Non so se si tratta di un problema di IIS o di un problema con la versione di IMB.Data.DB2.dll che sto utilizzando. Se qualcuno ha una soluzione o qualche idea, sarebbe molto apprezzato.
Grazie.
Grazie per la risposta. Ho provato questo e non ha funzionato. Sono stato in grado di capire il problema – user718300
