Trying to create a VNC map in visio 2003

[Jim]

I've built a simple floorplan drawing of my office layout with images
for eack PC terminal and attached VNC links via the add hyperlink
option to enable to me to monitor the other terminals. Clicking on
these links within Visio works fine, but when I save as a web page to
be attached to the company intranet, the links pop an error message
instead of opening the VNC window.

I have no knowledge of programming so any help would be greatly
appreciated (and also in layman's terms!)... Thanks in advance

Jim
