Я работаю над сайтом ASP.NET, который вызывает базу данных DB2. У меня есть Visual Studio, установленная на сервере Windows 2008, где будет размещен сайт. Когда я отлаживаю сайт в Visual Studio, используя встроенный веб-сервер, я могу подключиться к базе данных, и сайт работает нормально. Когда я устанавливаю сайт в IIS7 на том же сервере, я не могу получить доступ к сайту или базе данных из-за следующей ошибки.
Вот технические подробности:
Windows 2008 Server
IIS 7
Visual Studio 2010 Premium
DB2 v9.5.301.436

Я не понимаю, как сайт может нормально работать с веб-сервером Visual Studio и не работать в IIS. Я не знаю, была ли проблема IIS или проблема с версией IMB.Data.DB2.dll, которую я использую. Если у кого-то есть решение или какие-то идеи, они будут очень признательны.
Спасибо.
