The specified module could not be found. (Exception from HRESULT: 0x8007007E)

[Andre Lie]

I have an ASP.NET 2.0 application that works fine on Windows XP Professional and IIS 6 but has problem when I migrate it to Windows Server 2003. I understand that there have been a few similar postings but I still cannot understand the cause of this problem.

The error message is:

An unhandled exception was generated during the execution of the
current web request. Information regarding the origin and location of the
exception can be identified using the exception stack trace below.
