Remote Desktop connecttion

Trying to connect between work and home w/ xp pro at home and xp home at work
(realizing that I cannot go from pro version to home version ). I can connect
to other computers on our LAN at work remotely but when I try to dial into
home I get the error message: client cannot connect may be too busy try again
later etc... both locations have  linksys routers. Does remote desktop
automatically configure the router to allow computers in? Or do I manually
have to change a setting on the router... if so how?

You need TCP Port 3389 open on your router at the home end. Call the home PC
using the public IP of the router, ie. the IP assigned by your home ISP.

http://theillustratednetwork.mvps.org/RemoteDesktop/RDP6ConfigRecommendations.html

Ignore the references to UDP Port 3389 on the following pages...You only
need TCP Port 3389...

I also suggest consulting with your work network administrators. There may
be company policies against connecting an untrusted system (your home PC) to
a trusted network (your office LAN and PC).

great I will try that now...
same procedure going from home to work? same router linksys... different
computer connecting to at work (xp pro)
and if so do I have to specify the exact ip address of the work computer in
the port forwarding procedure (it's set up as a static ip so I know it will
periodically change)
again I know there are security issues but the host computer does need a
password to be accessed
-by the way that port forwarding website was exactly what I have been
looking for, it was great

Yes, use the same procedure. Its also possible to run Remote Desktop through
a VPN or SSH tunnel for added security if your work network administrators
only let you connect that way...

Make sure that when you test at home from another PC on your local LAN that
you call using the private IP of the PC you want to connect to. Its not a
valid test if you use the public IP...

http://theillustratednetwork.mvps.org/RemoteDesktop/TroubleshootingDiagrams/Basic.html

To properly test the public IP you need to be at a remote location.

If the canyouseeme test fails from the PC you want to access and the local
test, detailed above, passes then it comes down to a port forwarding issue
in the router or your running a firewall somewhere that is blocking TCP Port
3389 incoming.

tried connecting from another computer in my house on the lan  using the
private ip address of the host computer and it times out on the connection...
also... when trying to connect from the outside source... I should be using
the private ip address found in the cmd ipconfig/all section correct? not the
public ip address of the router

If you test over your local LAN and you can't connect then you have an issue
on the PC you want to remote connect to. Check the windows firewall or any
other software firewall you may be running on the PC to make sure TCP Port
3389 is open. There is a troubleshooting section on the page I pointed you
to in an earlier reply. If your running a Cisco VPN client or NAV worm
protection or OneCare Live those all may block incoming RDP requests if not
configured correctly.

http://theillustratednetwork.mvps.org/RemoteDesktop/RemoteDesktopSetupandTroubleshooting.html

Again, when calling the home PC from a remote location like work, a friends
house, etc use the *public IP* of the router. When testing over your home
LAN use the *private IP* of the PC.
