Question

I have recompiled Qt with integrated dbus for windows.

Further, I have implemented a QtService application which registers a service a

Answer 1

In the end I solved the problem and my service is now able to connect to the system bus.

I made the following changes:

In system.conf I changed the listen property and the authentication property:

<listen>tcp:host=localhost,port=13337,family=ipv4</listen>
<auth>ANONYMOUS</auth>
<allow_anonymous/>

According to that changes I set the system environment variables analogously:

DBUS_SYSTEM_BUS_ADDRESS = tcp:host=localhost,port=13337,family=ipv4
DBUS_SYSTEM_BUS_DEFAULT_ADDRESS = tcp:host=localhost,port=13337,family=ipv4

This answer led me in the right direction.
