remote connection problems...

By UncleRob ·
Having problems connecting remotely to another pc that I have setup at a friend's house.
We recently setup a wireless router and hooked up his laptop w/ a wlan nic to provide him with high speed internet access via a wireless connection. We then picked up a wireless pci card for his older desktop pc and did the same thing. Both his laptop & desktop pc are running xp pro & connected to the internet using a wireless lan connection. The wireless router being used is an older Netgear 4 port wireless router (80211b standard, not G), the wireless nic's being used are both netgear brand as well, a pcmcia card for the laptop & a pci card for the desktop. Stuff he picked up on ebay.

Both workstations can access the internet just fine. We can connect the laptop to the workstation & vice versa using a RDP session, that works fine from both machines. We have installed RealVNC v4.1.1 on both machines however here's the kicker, I can only connect to the laptop from the workstation using RealVNC, not vice versa.
I can ping both machines from each other using IP address (ex. 192.168.0.2 or .3) or by device name, so the machines can see each other. They can both access the router config page by entering the router's ip address and securely login to view & change settings. Wireless lan settings on both workstations are the same, both obtaining IP's via dhcp (the router), gateway, dns & wins settings obtained automatically as well. We can access file shares on both machines from each machine. However, RealVNC will not work from the laptop to the desktop. Using M$ Remote desktop works but it isn't interactive, it disables the existing user session to initiate the remote session and we would like to get an interactive session running. He uses the laptop for himself and the kids use the desktop.
We tested and the same problem when we use wired connection. Any ideas as to why RealVNC isn't working?

I hate to ask this but do you have the xp firewall disabled on the machine you are not able to connect to?

Thanks for the response, I'm sorry I forgot to include this info in my original post, the firewall service has been disabled on both the laptop & workstation.

Sorry, I didn't mention this in the original post, XP's Firewall service has been disabled on both machines.

sorry, i had trouble following your post all the way. but i think it is clear enuf. you sure the laptop didn't previously have a firewall product on there that has been uninstalled (like zonealarm)
you tried another user profile?
you think you might need a port forward in the router? aren't the laptop and the desktop both gonna look like they are at the routers ip address from outside their lan?

Thanks for the response,
no firewall service of any kind has been enabled on the laptop or the workstation. I will check out what is required for port forwarding on that router, I've never messed with anything like that before but it can't hurt to try.
I'm not necessarily worried how these devices look outside the LAN since I'm only interested in how they interact while connected in this LAN , the router provides each of these connections with a unique ip address so I don't think that is causing the problem. Thanks for the response, I will check out port forwarding and what it entails and let you know if it helped.
