Wez,

I have done this about 20 times.  Even after you provided the switches to
get a log file, that is exactly what happened, it opened, asked for the IP
address, I provided that and then it flashed a very brief (almost
unreadable) "trying to connect" message, and leaving an instance of VNC
running each time I tried this.  I did not have a C:\Temp dir and the switch
did not create one to place the log file in.  

I then created a temp dir, but it was in the c:\Program Files\ directory, at
which point the symptoms changed.  The log file was still not created of
course, because the temp dir was in the wrong place, but it began to leave a
message window open - "Attempting to connect to host", which eventually
timed out and popped up "unable to connect to host: Connection timed out
(1006).  I then discovered the wrong location of the temp dir and created
one in c:\ at which point the log file was created.

Something has changed.  I went back and deleted the C:\Temp as well as the
c:\Program Files\Temp dir. To see if the message went back to a brief flash.
The VNC still pops up and leaves the error message up (attempting to
connect), and does not leave an instance running but not visible.

What was happening originally is something I can't help you with.  I can
tell you that it only occurred when attempting to connect with the
sister-in-law's machine, i.e. I have always been able to vnc in to my client
from the same laptop.

Now I still have to figure out why I can't connect, but at least the "can't
connect" message stays up and doesn't leave an invisible instance of vnc
running every time.  I am attempting to connect within the network (over a
wireless router) to machine 192.168.0.2 running the VNC4 Server.  The server
IS at local IP 192.168.0.2 according to IPConfig on that machine.

OK... It appears that the machine is "powering down" or going into a sleep
mode.  When I go up and wiggle the mouse, the machine comes up and then I
log on.  After that I get the same symptoms described initially, i.e. it
asks for the IP address but then just creates an invisible instance of VNC4
viewer.

Is it possible it has to do with "fast user switching stuff" on XP?  There
are two users defined and when the computer comes out of sleep mode (wiggle
the mouse) I have to select one of the two users but seem to be instantly at
the desktop for that user, whereas on my laptop machine after keying in my
password it takes a minute or so to "finish booting".  At any rate...

The following is the current contents of the log file after one attempt to
connect, leaving an invisible instance:

John,

I'm afraid I'm very confused now.  Originally, you said that VNC Viewer
briefly popped up the Connecting dialog and then took it away again, but did
not quit.  Your log output indicates that it is indeed trying to connect and
is then failing, putting up an error message indicating that the host to
which you are trying to connect is not contactable within the specified
timeout, and then quitting.

Can you clarify what the actual problem is that you are seeing?  Have you
checked whether you can telnet to port 5900 on the problem machine?

BTW, we seem to have gone off-list - please remember to use Reply-To-All to

Cheers,
