Chapter 2: Getting Connected
If this is unacceptable and you are connecting to VNC Server (Enterprise) or VNC Server (Personal), you
may be able to turn encryption on. Click the Cancel button and see Changing the encryption rules on
page 109 for more information. Otherwise, click Continue.
Entering authentication credentials
You may be required to enter a user name and/or a password:
By default, if you are connecting to:
• VNC Server (Enterprise) or VNC Server (Personal), enter the credentials of a user with administrative
privileges on the host computer. If you:
— Do not know such credentials but have access to the host computer, you may be able to find them
out, or alternatively register your own credentials. If you do not have access, contact a system
administrator or a host computer user.
— Know that the primary user account does not have a password set (likely for friends and family only),
then you must change the default authentication mechanism, or disable authentication altogether.
For more information, start with Authenticating using host computer user credentials on page 98.
• VNC Server (Free), enter the VNC password, leaving the Username field blank. If you do not know this
password but have access to the host computer, you may be able to reset it; see Authenticating using a
VNC password on page 103 for more information. If you do not have access, contact a system
administrator or a host computer user.
Click the OK button. If the connection succeeds, 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 the connection details 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.
