I have a strange issue with remote control. The service installs ok on client and run correctly but port 5900 is not opened. If a run winvnc.exe on client manually, the port is opened and remote control goes ok.
I've tried with procmon. , too much information for me. The errors that I saw were about registry keys not found and files not found, about winsock nothing.
The problem are in two domains on two separated networks. I discard GPOs and FireWall.
