successfully authenticated to a network when logging on to your client computer. For more information, see
Authenticating automatically using client computer user credentials on page 105.
You can disable this feature if you want to connect to VNC Server using the credentials of a different user.
This might give you access to more VNC features while the connection is in progress. To do this, turn off
Use single sign-on if VNC Server supports it on the Connection tab.
Configuring printing
By default, when you connect to VNC Server (Enterprise) or VNC Server (Personal), your client computer’s
default printer (if it has one) is shared with the host computer and made its default while the connection is in
progress. This means you can print host computer files directly to your local printer. For more information
about this feature, see Printing host computer files to a local printer on page 60.
You can print but choose not to change the host computer’s default printer. This means you will have to
explicitly select your printer when you print. To do this, turn off Make it the default printer on VNC Server
on the Printing tab.
To disable printing, choose Don’t share a printer.
Connecting to a host computer
This section summarizes how to connect from a client computer running VNC Viewer to a host computer
running VNC Server. For a step-by-step guide, see Chapter 2, Getting Connected on page 19.
1. Start VNC Viewer on the client computer. The VNC Viewer dialog opens.
2. In the VNC Server dropdown, enter a private or a public network address for the host computer, qualified,
if applicable, by the port number on which VNC Server is listening, for example 192.168.0.133:1.
3. From the Encryption dropdown, select an encryption option, or retain the default: Let VNC Server
choose.
4. Click the Connect button.
You may be asked to confirm a VNC Server signature, acknowledge the encryption status, and authenticate
to VNC Server.
If the connection is successful, VNC Viewer displays the host computer’s desktop in a new window on the
client computer. Carry on from The VNC Viewer user experience on page 38. If the connection fails for any
reason, start with Troubleshooting connection on page 26.
Note: Once connected, you can save a connection so you can quickly reconnect without having to
remember the network address and authentication credentials. For more information, see Appendix A,
Saving Connections on page 121.
