I see VNC showing up as an app but cannot find it installed on PC. We only have 1 PC that we support VNC on. So Im trying to figure out what this person is doing. I cant create a rule to block the port as the one PC needs it. How doe sAerohive classify the VNC app? by port? could this be someo other virtual network computing on this PC?

Aerohive's application visibility uses source and destination ports as a coarse-grained determination of the applications traversing our access points, and for commonly-used ports we do deeper inspection for application-specific messages to narrow down to a specific application.

The default listener port for VNC server is TCP 5900, I believe it also listens on TCP port 5800 specifically for Java-enabled clients. 

Yes, it is possible for this to be a mis-identification and your user is running some other application that happens to use TCP port 5900-5999...
