I've used the ATL COM wizard of VC++ 5.0 to create a COM server that runs as a service.

The service is able to install and it runs when I try to retrieve an interface. The problem I'm having is that when I use CoCreateInstance to create
an instance of the interface, it returns with the error "Bad variable type."

I've created this server as both a DLL and a non-service EXE. Leaving the client unchanged, CoCreateInstance does not throw an error when using the other two versions. It only errors when the EXE is installed as a service.

Any insight into this problem would be appriciated.

Thanks,
Matt Johnson
