VNCHelp installs the VNC software on Microsoft Windows 9x and Windows
NT/2k/XP/2003 workstation and server platforms. VNCHelp is an extention of
the VNCPull application where the user "pulls" the VNC software for
installation in contrast to the VNC software being "pushed" as with VNCPush.
VNCHelp extends VNCPull by utilizing the reverse connection method to allow
internet based support and works around firewalls. Like VNCPull, VNCHelp is
a pre-configured installation where the user runs the vnchelp.exe program to
install and start VNC and to completely uninstall VNC including all registry
entries. VNCHelp extends VNCPull by also connecting to a pre-configured IP
address. This pre-configured IP address would be the router of the support
network where port 5500 has already been opened and routed to the engineer's
workstation IP address.
VNCHelp is used where the engineer does not have configuration access to the
network router / firewall where the user's computer resides. This includes
home users with a Linksys router running NAT as well as corporate LANs. The
connection is initiated by the user's computer (the VNC server) back to the
engineer's computer (the VNC viewer running in daemon mode), therefore the
NAT mappings and firewall rules are opened as with normal web browsing.
VNCHelp - Features
VNCHelp features include, pre-configured package that installs and uninstalls
the VNC server software with a mouse-click as well as automatically
initiating a reverse connection thru a user's firewall to a pre-defined IP
address where an engineer is running the VNC viewer in daemon mode.
VNCHelp is written in the MS-DOS Batch scripting language. This language is
fully compatible with Microsoft Windows 9x and Windows NT/2k/XP/2003
workstation and server platforms.
