The Video Streaming page establishes a remote control session between the VSA user's local machine and a machine without an agent. Use it to help someone quickly on an infrequent basis. If you plan to provide continuous support we recommend you install an agent.
The following conditions apply:
Note: Use Control Machine to remote control a target machine that has an agent.
If WinVNC, K-VNC or RAdmin are not installed on a machine and a remote control session is initiated using Control Machine or Video Streaming, then these packages are automatically installed. Installation does not require a reboot. Automatic installation takes up to an extra minute.
When either side terminates the Video Streaming session, the remote server on the target machine uninstalls automatically, removing all remote control files and registry additions.
An ActiveX control automatically configures and runs the remote control or FTP package for you. The first time you use any remote control or FTP package on a new machine, your browser may ask if it is OK to download and install this ActiveX control. Click yes when asked. If the ActiveX control is blocked by the browser from running, the user is presented with a link to manually download and run the remote control package manually.
In setting up a remote control or FTP session, gateway and port blocking problems are eliminated by always initiating outbound connections from both the target machine and the user machine. Helper applications, unique to each supported remote control or FTP package, automatically determine the optimal routing path between the VSAuser machine and the remote machine. If a direct connection is not possible then the helper applications route the remote control traffic through the KServer on the same port used by agents to check-in (default 5721).
Remote Control Malfunctions
Some reasons for remote control failure—for target machines with and without an agent—are:
Click the Start button. Ask the remote user to display the
Enable verbose relay
Remote control or FTP of machines behind firewalls and NAT gateways may be relayed through the VSA server using a helper application. Checking this box displays a popup window with status information about the normally hidden helper application.
Select remote control package to use
The default remote control service uses WinVNC. See Select Type for a description of the different types of remote control packages.
Specify the default HTML message seen by users when no administrator is waiting to help.
This is the message displayed if the remote user displays the
