im not 100% sure but isn't it that you can't control 2 computers under the same ip address

@jack i'm not saying this is correct at all. I am curious my self

When you connect to a PC in your network it's using a private IP address and they can talk to each other.
Those private IP addresses are not available on the internet connection.
You only have one public IP address on the internet.
A router will control sharing the internet connection between all the private IP addresses.

@jd i am trying to connect using the pc ip address not the internet ip

@whs it is a hub/switch

@pooper they don't have to be under the same ip and it is used to have remote access to other pc's

As I understand it, sharing via a switch is not possible with all modems. I happen to have a Netopia modem where it works. I'LL have to dig to find the details.
Edit: Ok jack, here it is. It was your own thread: http://www.howtogeek.com/forum.....replies=25

@jack: I think whs was thinking maybe you had a switch that didn't work to share things.
Also I was a little confused by your description of your network and what you want to do.
Can you list it in a tree like the following?
Internet
- Modem
-- Switch
--- Computer A, PC to be controlled with VNC
--- Computer B, PC to connect to Computer A
--- Computer C, Just sitting there

ok here this is kinda hard to explain

-switch
-pc 1:internet connection using wireless usb internet modem pc to connect to pc 2
-pc 2:internet shared from pc 1 and to be controlled by vnc
-pc 3:internet shared from pc 1

Ok so it's like this then:
- Switch
-- PC 1
--- Modem
---- Internet Connection
-- PC 2, connects to PC1 via above switch for Internet, to be controlled with VNC
-- PC 3, connects to PC1 via above switch for Internet

Now which one PC 1 or PC 3 are you using to connect to PC 2?
If both which isn't working?

So connecting to PC 2 with VNC from PC 3 works and from PC 1 it doesn't or does it not work from either?

If you can't connect from any computer then either the firewall or VNC server on PC 2 isn't configured to allow connections from other computers.
Do you have a firewall on PC 2? If so you need to allow access to the VNC server.

Ok. In that case then VNC Server might not be configured to accept incoming connections.
I've noticed that RealVNC isn't always configured by default to accept incoming connections.

It depends on your subnet and version of VNC.
Do you use the Internet Connection sharing built in to Windows?
Do you use RealVNC?
If the answers are yes I can tell you how to configure it.
If the answers are different I can probably tell you how but I'll have to check how to do that.

I just remembered, what OS are using on PC 2?
The last time I tried RealVNC on a Vista machine the connection was a little slow.
