Using remote control utility VNC running as a service on a workstation that needs to be remote controlled. This workstation runs several applications in virtual machines (NTVDM). VDM's tend to run at 98% CPU utilisation. Since the VDM and VNC both run at process priority of normal (8), the remote control response is slow. I want to increase the process priority of the VNC service to high. With VNC running as a service, how can I change its priority???? Have tried the usual Task Manager, process, set priority etc., but get Access Denied. If I run VNC as an application instead of a service (Start /High C:\RealVMC\WinVNC.exe), I am able to change the priority but this is then not running as a service. Have tried configuring the exe with SRVANY without success.
