When you try to access either the OLE DB Provider for DB2, the ODBC Driver for DB2, or the OLE DB Provider for AS/400 and VSAM in Microsoft Host Integration Server 2004 from an Active Service Pages (ASP) page, the process fails and you receive the following error messages:
For OLE DB:ADODB.Connection (0x800A0E7A)Provider cannot be found. It may not be properly installed./Path/FileName.asp, line number
For ODBC:Microsoft OLE DB Provider for ODBC Drivers error '80004005' Specified driver could not be loaded due to system error 5 (Microsoft ODBC Driver for DB2). /Path/FileName.asp,line number
By default, anonymous access to ASP applications uses the local IUSR_COMPUTERNAME account and ASP.NET applications use the local ASPNET account. To resolve the behavior that is mentioned in the "Symptoms" section, add either the IUSR_COMPUTERNAME account or the ASPNET account to the HIS Runtime Users group. After the appropriate account has been added to this group, you must restart Microsoft Internet Information Services (IIS) for this change to take effect.
