Cannot start service instance for NAV

Hi all,

I know that this is not a new topic, but I still didn't find solution for my problem.

When I try to start NAV service instance, he start and stop immediately. EventViewer show me this error message



Just to say that Net Tcp Port Sharing is running.

I tried almost everything to solve this: change ports in config file, in firewall. Install NAV again, start instalation in repair mode...

If anyone have any idea what else I can try, I would be very grateful.

Thanks,

Stefan
