[Jerry Westrick]

Hello Andrea:

FIrst off, don't give up, we'll get you the information you need...
Although it may take a while 8-)

Here goes a little drawing to show what I understood:

     INTERNET
        |
        | 151.133.10.55
 +------+-------+ 
 | Internet PC |
 +------+-------+
        | 199.168.33.01
        |
        |  199.168.33.??  +------+
        +-----------------+ PC 1 |
        |                 +------+
        |
        |  199.168.33.??  +------+
        +-----------------+ PC 2 |
                          +------+


I understand that vnc conections between PC-1 and PC-2 work when the
internet sharing is off.  

And that the vnc connections does NOT work when internet sharing is on.

And lastly you have a more questions which I did not understand...8-(


ANSWERS

VNC requires a working TCP/IP system.  when the TCP/IP system works then
you get a connection.  When it doesn't you don't.  What I think your
problem is that the TCP/IP is not configure correctly when you have
internet sharing on!  To test this you can do the follwoing:

1) start internet sharing
2) in DOS-BOX  try to ping each machine with "PING 199.168.33.xx".
3) do this on all machines...


If this does not work then you have a TCP/IP problem, which must be
fixed before VNC can work.



COMMENTS:
a correct ping looks like this:
==============================================================

C:\Documents and Settings\jerry>ping 10.0.0.198

An incorrect ping looks like this:

I hope this helps a little
