Can't create object when browsing ASP pages

This article helps you resolve the error (Cannot create object) that occurs when an Active Server Pages (ASP) application runs.

Original product version:   Active Server Pages
Original KB number:   201740

Symptoms

When an ASP application runs, you might receive the following errors:

Application Event Log error:

Failed on creation from object context: CoCreateInstance (ProgId: ADODB.Connection.1.5) (CLSID: {ID}) (Microsoft Transaction Server Internals Information: File: d:\viper\src\runtime\context\ccontext.cpp, Line: 1292)

Browser error:

Microsoft VBScript runtime error '800a01ad' ActiveX component can't create object /test.asp, line 1

The line in the ASP file reads as follows:

<% set db = Server.CreateObject("ADODB.Connection") %>

Cause

This problem is related to the permissions granted to your dynamic link libraries (DLLs). The IUSR_computer and IWAM_computer accounts (where computer is the name of the machine) don't have the permissions necessary to execute the DLLs being instantiated on the Server.CreateObject line in the ASP code.

Resolution

The IUSR_computer and IWAM_computer accounts must be granted read permissions to the \<drive letter>: \Program Files\Common Files\System\ADO directory.
