800a01ad error while debugging VB6 DLL under IIS6.0 on Win2003SP1

Configuration: Windows Server 2003 SP1, IIS6.0

A VB6.0 DLL works fine when called from ASP page without debug mode. However
when I try to run it in debug mode using Visual Studio 6 IDE I am getting
following error:

Microsoft VBScript runtime error '800a01ad'
ActiveX component can't create object

The test code is very simple and given at the end.

I tried the following to run the dll in debug mode and to invoke from the
ASP page but nothing worked.

- Grant full control permissions at OS level to all users (‘Everyone’) for
the folder where DLL resides.
- Created the “VB ASP Debug” entry in DCOMCNFG by modifying the registry and
then giving proper permissions.
- Checked all permissions within the “Directory Security” tab within IIS
- Given read permission to everyone for DLL entries in registry.
- Added appropriate users in ‘Debugger Users’ (under Computer Management,
System Tools, and Local Users and Groups)
- Used RegMon, FileMon and ProcessMon but not get much information.
- There are no event log entries in the application/System event log.
- In DCOMCNFG set proper permission for ‘Debug Machine Manger’ as well as
test DLL.
- In IIS tried changing user authentication modes (under Directory Security)
- Given read permission to ‘Everyone’ to “C:\Program Files\Common Files”
- Given permission to ‘Everyone’ by opening Properties of DCOMCONFIG and
then selecting COM Security.
- Given IIS_WPG, IUSR_ AND IWAM_ accounts both have
Read/Execute NTFS rights on the following folders cascaded down.
- \program files\common files\System
- \Windows
- \InetPub\WWWRoot
- Reinstalled SP1


Checked following KB sites:

http://support.microsoft.com/kb/259725

VB Code:
(CompileTest.DebugME)
Public Function TestMe() As String
TestMe = "TestOK" ‘ put debug point here
End Function

Asp Code:

<%
set objTest = Server.CreateObject( "CompileTest.DebugME" )
Response.write(objTest.TestMe())
%>

RE: 800a01ad error while debugging VB6 DLL under IIS6.0 on Win2003SP1

This issue is causing because of terminal server. This issue not causes if VB
dll debugged on server itself.
I am looking for possible solutions to debug it using terminal server. There
is one KB article on it but not that much helpful:
