>I have a dll registered in MTS to work with ASP pages. We wrote a C++ dll to do some communications through a dedicated line to one of our business partners. I can declare and use the dll just fine from the class def in VFP or even when compiled into a COM dll, but as soon as I add the COM dll to MTS, it stops working. It reports "Error in declare ..." but it actually reports it on the line that calls the dll function.

I have also noticed that in my event viewer, I have error saying that the threading model has changed and that I should reinstall the COM+ application.

Is it possible that as soon as the C++ dll function is called, MTS sees a new threading model or something to that effect? I'm not really all that VC++ or threading models for that matter.
