Waiting for server to send version string... failed: (111, 'Connection refused')

[Dean Buck]

G'day everyone,

I am having the error "Waiting for server to send version string... failed:
(111, 'Connection refused')" when I use the VNC SERVER TEST PAGE.

VNC server is setup and running on a vista home x64 machine.  I am behind a
dlink dl-624s router.  The ports 5500, 5800 and 5900 are forwarded to my
computer.  I have peer guardian, avast, and spybot running.  I have
disabled/closed all of these and still have the problem.  I do not have
windows firewall running.

Anyone have suggestions as to why I can't see the VNC server running?
 Thankyou in advance.
