UVNC is a great open source program for connecting to servers or PC’s. One of the major setbacks however is the difficulty in installing UVNC while connected with Remote Desktop, or RDP. The problem is it will run as the signed in user and even if you are signed into the console it still doesn’t seem to work right. Here are a couple of batch files I have written to uninstall UVNC and then another to reinstall UVNC. These can be used with a Remote Desktop (RDP) connection or through command line as well. To use these, simply copy the contents into a text file and save as UVNC-Uninstall.bat or UVNC-Install.bat.

Connecting VNCViewers
-connect host[:display]- Adds a new client to an existing copy of winvnc.
Needs the computer name (DNS name) or IP address and optionally the display number (separated from the host name with a colon (:). -connect host[::port]- Adds a new client to an existing copy of winvnc.
Needs the computer name (DNS name) or IP address and optionally the port number (separated from the host name with two colons (::). -autoreconnect- Is used in conjunction with the
-connectswitch when having a server “back-connect” to a listening viewer. You can use it in a batch file for your clients that are behind a firewall that is not under your control. The batch file looks something like this:
"c:\program files\ultravnc\winvnc" -autoreconnect -connect 12.34.56.78
On the local computer run the viewer in “listening” mode, and have someone on the server end run the batch file. The-autoreconnectwill make the server end attempt to reconnect to the listening viewer if the connection drops or is closed. It will immediately reconnect to the listening viewer if the session is closed. Close the listening viewer altogether in order to stop the server end from “autoreconnecting” to your computer. The server attempts to “autoreconnect” for only a few seconds.
Note that this “autoreconnect” param must be before the “connect” one on the command line! -kill- Kills any already running copy of WinVNC.
