I prefer TightVNC over UltraVNC, essentially because they have viewers also for other operating systems and I'm not stuck on browser/java viewer under my preferred OS.

I install and manage TightVNC with the following XML package description:

 <package id="tightvnc" name="TightVNC server" revision="129" priority="50" reboot="false">
        <check type="uninstall" condition="exists" path="TightVNC 1.3.8" />
        <install cmd="%PACKAGES%\tightvnc-1.3.8-setup.exe /sp- /verysilent" />
        <install cmd="%ProgramFiles%\TightVNC\WinVNC.exe -reinstall" />
        <install cmd="%ProgramFiles%\TightVNC\WinVNC.exe -servicehelper" />
        <install cmd='cmd /c netsh firewall add allowedprogram program = %ProgramFiles%\TightVNC\WinVNC.exe name = "Launch TightVNC Server"' />
        <upgrade cmd='%PACKAGES%\tightvnc-1.3.8-setup.exe /sp- /verysilent' ><exit code="0" reboot="true" /></upgrade>
        <upgrade cmd="%ProgramFiles%\TightVNC\WinVNC.exe -reinstall" />
        <upgrade cmd="%ProgramFiles%\TightVNC\WinVNC.exe -servicehelper" />
        <upgrade cmd='cmd /c netsh firewall add allowedprogram program = %ProgramFiles%\TightVNC\WinVNC.exe name = "Launch TightVNC Server"' />
        <remove cmd='"%ProgramFiles%\TightVNC\WinVNC.exe" -remove' />
        <remove cmd='"%ProgramFiles%\TightVNC\unins000.exe" /silent' />
</package>
 
 <package id="tightvnc-settings" name="TightVNC server settings" revision="3" priority="5" reboot="false" execute="once">
        <depends package-id="tightvnc"/>
        <install cmd='cmd /c "%WPKGROOT%\packages\tightvnc.bat"' />
        <upgrade cmd='cmd /c "%WPKGROOT%\packages\tightvnc.bat"' />
        <remove cmd='echo "nothing"' />
 </package>

TightVNC is a simple batch script that setup TightVNC server and restart it:

 :: start, restart or apply settings to tightvnc
 ::
 net stop "VNC Server"
 regedit /s %WPKGROOT%\packages\tightvnc.reg
 net start "VNC Server"
 
 :: For some unknown reason the servicehelper does not restart.
 ::
 %ProgramFiles%\TightVNC\WinVNC.exe -servicehelper
 :: we ignore errors...
 ::
 exit 0

tightvnc.reg contains the setup of the server, most notably the access password, i.e. I can use as a registry patch:

Windows Registry Editor Version 5.00

NOTE that passwords are crypted, but this is no a paranoid setup, someone can easily have access to the registry patch and try to decrypt the password.
