I have created a simple MTS aware VB DLL which calls SetComplete. I am running on Win2000 and so have referenced COMSVCSLib as opposed to MTxAS. I have set up the package and component in MTS and created a test program.
When I run the test program the code functions as expected but the transaction does not register, although no errors are reported and the package in MTS keeps spinning. I have tried the same code on NT and Win98 (with MTxAS referenced) and it does register a transaction. Therefore I imagine it is something to do with set up of MTS on 2000.

Can anyone help me??
