Question : Problem: Log VNC access.

I have a vendor who connects remotely to his servers on our site.  He connects to our site via a VPN which allows him to run an RDP session on a management server. From the management server he can run VNC to connect to any of his servers.
I would like to create a log of every time he uses VNC to connect to one of his servers. Ideally, this would be a single log stored on the management server. All I need to keep track of is the Date, Time and IP address of the server to which he connected.

Is there a reasonably straightforward way of doing this?

Answer : Problem: Log VNC access.

If VNC server is running as a Service, then it logs by default to the Applications section of the Event Viewer logs on each client machine....unfortunately VNC doesn't contain an option to change the path.

You can get all the event logs for each machine in a central location though - see the following link:

Hope this helps
