80040155: Automation error Interface Not Supported

80040155: Automation error Interface Not Supported

80040155: Automation error Interface Not Supported

I am creating a web application using ASP and Visual Basic COM objects for my business and data access layer. The COM data access layer (ActiveX dll) runs under MTS. The VB business layer (ActiveX dll) does not. I have all the layers installed on the same NT 4.0 server SP6a (IIS / business layer / data access layer under MTS). When the business layer ActiveX dll tries to call the data access layer, I get the error 80040155: "Automation error Interface Not Registered" on my CreateObject statement in the business layer. However I can export the MTS package on to another PC and be able to call it from my business layer running on the second PC. Any ideas or suggestions to fix this would greatly help.

Big chances that some component (DLL) is missing from your mts server.  I had a similar problem "Interface not supported" when I used the Date-Environment of VB and solved it when I installed Visual Interdev Server Components
which installed a file "msderun.dll", or you can try to register it manualy.
