Simple remote connection on Windows Edit

This is a remote desktop setup with VNC, where the user only needs to double-click a connect.bat file in order to request a remote desktop connection. It installs a display driver for you to ensure more optimal throughput (only transmits parts of the screen that are changed).

Usual disclaimer: No guarantees. Please share experiences. It works on Windows XP SP2 setups. I have had reports that it worked on Vista, albeit it might have needed some permission/firewall tweaks.

I wasn't sure how licenses were for the different applications, so i wanted to start with references to what's needed and only supply a howto guide. I might package some of the stuff, if i gather info on all of the licenses.

Client setup Edit

  • Make a folder for the helpdesk application (e.g. c:\helpdesk) and a subfolder for the dependencies (e.g. c:\helpdesk\program)
  • Extract winvnc.exe and VNCHooks.dll from the TightVNC set of executables (don't need the installer) into the c:\helpdesk\program folder
  • Download the DFMirage driver (dfmirage.exe) into the c:\helpdesk\program folder
  • Extract sleep.exe from the Windows Server 2003 Resource Kit Tools into the c:\helpdesk\program folder
  • Make a c:\helpdesk\program\setup.reg file with the following contents:
Windows Registry Editor Version 5.00

echo Connecting...
program\winvnc -kill
start program\winvnc -run
program\sleep -m 500
program\winvnc -connect %address%

Host setup Edit

For the person that wants to take over the other computer (the sysadmin), you merely need to start any VNC viewer (perhaps TightVNC), with the -listen argument:

vncviewer -listen
