Help Connecting

[James Weatherall]

Robert,

Firstly, I'd strongly recommend using a version of VNC with in-built session
security such as VNC Personal or Enterprise Edition, or running VNC through
a secure tunnelling protocol between the two systems.

At a guess, I'd say its most likely that you have tried to connect to the
server computer too many times, and so your viewer IP address has been
"blacklisted" for a short while, in defense against potential brute-force
attacks.  If you upgrade the server computer to a standard VNC 4 series
server then you can set it up easily to log information on connections,
including reasons for them being closed.

Cheers,

Wez @ RealVNC Ltd
