Hello,
I experienced the very same Problem here. I use Windows Server 2003 x64 Edition Service Pack2.
My use case: Some people have to use Pingplotter on this machine to alter the configuration or enter some targets. This has to be done on either way: logging in to the machine via RDP or using the builtin webserver.
Afterall, the given solution does not work for me. The service is configured to run by a special user. The Service is not configurable. The Application (if started) runs its own instance.
I hope there is another solution or workaround
