Screen Sharing PCs

With the introduction of 802.1x,  users are no longer able to use the native RDP connection on PC’s to remotely control machines. You can establish an RDP connection, but doing so terminates any network access on the connected machine. The following document is a workaround for using an alternative method using “VNC”.

Please remember if you are connecting remotely for the sole purpose of using NTM and Vault, that can be achieved without RDP or VNC through the AnyConnect SSL client.

Best practices

  1. Only use VNC when alternatives are not possible.  

  2. Tight VNC is the recommended product for PCs.  Macs perform this function natively and that should be used instead.

  3. For PC, after the Tight VNC server install, do the following:

    1. Configure a log in password

    2. Change settings so the screen locks after VNC disconnect.

    3. Inform users that their screen will be visible when in use.  Recommend they turn off their monitor / close office doors or take other precautions when planning to connect remotely.

    4. While in Finder, press the Command key+k on your keyboard. This will bring up the Connect to Server window.

    5. Input vnc://computername or vnc://ipaddress where computername (or ipaddress) is the name (or address) of the VNC server you wish to  connect to. If the server is using another port besides the default (5900), add a colon and the port number after the computer name (or address).

    6. Click the Connect button.

Windows Installation Instructions

  • Begin with the machine you want to remote into. After double-clicking the installer you'll see a screen with three install options: Typical, Custom, and Complete. Click Complete.

2) The next screen has several options regarding file associations, server options, and firewall exceptions. Make sure all boxes are checked and click Next

3) This screen is where you'll put in the passwords to authenticate your remote session. The second set of boxes is supposed to secure changes to the options later.  Please  set ta Password for remote access

4) After you set the password, click ok. Then Finish. At this point the VNC server is installed on the pc. The VNC server service is already started and set to start automatically when the machine boots. There is now an icon for TightVNC in the notification area that will alert the user by changing colors whenever someone remotes in.Configuration"

To configure the rest of the settings, click on the TightVNC icon in the system tray.  Set the Server tab as you see below, then click on the Administration tab and select “Logoff Current User” under the When Last Client Disconnects section.  (not shown below)

6) Click OK and you'll see a pop-up that states that the changes won't take affect until the VNC service is restarted. Click OK. If you don't know how to restart the service then don't worry. Just reboot the machine. Then go to the machine you'll be remoting from and we'll install TightVNC there.

7) Get the ip address of the machine.  This can be done by opening CMD prompt and typing in “ipconfig”. You will need this to connect to your machine later.

Installing the VNC Viewer

Note:  This is done on the PC you want to connect to your work machine from.

To connect from a Mac, VNC Viewer is built-in. In Finder, click on Go > Connect to Server, and in the server field, enter vnc://yourIPAddress  You will then be prompted for login info to get into the computer.  Make sure you enter your Domain Account and Wellesley for the Domain.

7) The steps are nearly the same for this machine except at the screen that says Typical, Custom, and Complete. Select Custom.

8) Highlight the TightVNC Viewer only.

The rest of the process is the same as installing the server. Make sure all of the check boxes are checked on the file association and options page. And enter the passwords you want to use. These passwords will be used if you choose to allow other to reverse connect to you and are supposed to protect access to the configuration settings.

9) Then click OK and then Finish.

Testing the Connection

10) It's now time to test our configuration. Open up the TightVNC Viewer on your desktop. In the Remote Host box put the IP to the remote machine. Then click Connect.

11) If all has gone well you should be asked for the password you set on the remote machine.


12) Success!!! You should then see the desktop of the remote machine.
