remote desktop connection xp pro

[peterjack01]

i have a complex problem that no forum has been able to help with yet.a client has got a home network ,it consists of :wireless adsl router connected to a pc via 802.11 ethernet port.2x laptops that have pcmcia wireless airway cards.his broardband is shared ok between all the computers.the sharing of files and such works fine between all of them.the problem know is that if you remote desktop connect to the pc connected to the router from any of the wireless laptops it cant get passed the router(if you ping its ip you getted blocked by the router ).all the pc's are in the same house .the router make by the way is a origa awr-8210.

i would apprieciate any feed back.by the way i tried vnc it did the same thing.

This is just a start as it could be many things causing this:

- From the PC (that you want to connect to), at a command prompt run "netstat -a" and make sure that TCP port 3389 is listening. This is the terminal services (remote desktop) port.

- The router is probably configured to block WAN requests that's why the pings are being blocked.

- It also could be that the router is just plain blocking the 3389 traffic. I don't use that model router but to configure Remote Desktop on my network (with a LinkSys router), I had to enter a Port Forwarding record. It basically gives the router the OK for that port and tells the router where to send the traffic on to. (This may not be the case for you because you are doing this internal, I needed the record so I could access from the outside.)

- Is there any firewall on the PC blocking this traffic?

- Can you use any of the other lower numbered TCP services like telnet or ftp to the PC?

thanks for the speedy reply.port 3389 is listening on tcp.im pretty sure it is the router blocking me from the pc .the manual that comes with the router is of the worst kind i have ever had the misfortune to work with.i can either scan it in and email it to you or you can go to www.adsltech.com and view it there,and see if you can make any sense of it .

the router is the 3rd one down on the list.on the website.

thanks again

when you mentioned a firewall ,i thought i would check again as i remembered he had pc-cillian in his programs.it was (what i thought not to be running)but turned out to be windows xp old problem where it doesnt show or looses its icons in the taskbar.very annoying to say the least.

a silly mistake i should have cheched in task manager.but so we learn.

thank you for your insight
regards

I'm assuming from that, it's working now?

If so, don't bring the firewall completely down (if you have). You should be able to configure the 3389 port for TCP traffic. That way you don't expose the rest of your system.

Another piece of advice I would offer for Remote Desktop, especially if this network can be seen from outside the router, is change the default port it runs on (3389). Here is an article on it and how to make the change.
