dialup or broadband it doesnt connect


please suggest what do i do to solve this problem and connect from any
computer with any ISP

How are you calling, ie. IP or fully qualified domain name? Any firewalls between you and the public
internet? Any chance your ISP blocks TCP Port 3389 inbound? See this page for some troubleshooting
help.

first i will tell u how i am trying to connect

scenario 1#

1. host computer stand-alone connected to the internet with a cable
modem(motorola-surfboard)
i have installed no firewalls nor has the isp installed any firewalls on the
host comp in my knowlegde

2.client comp stand-alone connected to the internet with a cable modem
(motorola-surfboard) same isp as host comp

remote desktop connection successful

scenario 2#

1. host computer stand-alone connected to the internet with a cable
modem(motorola-surfboard)
i have installed no firewalls nor has the isp installed any firewalls on the
host comp in my knowlegde

2.client comp stand-alone connected to the internet dialup

remote desktop connection unsuccessful

scenario 3#

1. host computer stand-alone connected to the internet with a cable
modem(motorola-surfboard)
i have installed no firewalls nor has the isp installed any firewalls on the
host comp in my knowlegde

2.client comp in network connected to the internet using wireless broaband

remote desktop connection unsuccessful

MY POINT IS THAT

-REMOTE CONNECTION IS SUCESSFUL ONLY IF I USE THE SAME ISP AT BOTH ENDS (
HOST AND CLEINTS )

WHAT I WANNA DO IS

REMOTELY CONNECTION WITH ANY ISP (DIALUP, WIRELESS BROADBAND , CABLE )

PLEASE HELP ME OUT
 
Well the only thing I can think of is to double check the Windows Firewall and make sure the
firewall is either disabled or if its enabled to make sure the Remote Desktop address "Scope" is set
to "Any computer (including those on the internet)" versus the default "My network (subnet only)".

hi sooner , well thanks for the solutions , though my host computer is a
windows server 2003 amd i cant find this win0dows firewall anywhere

thanks
 
Well, its possible its an issue with either Windows 2003 Server or Terminal Services. I suggest you
post to this news group for help since I don't believe its a Windows XP Remote Desktop issue...

microsoft.public.windows.terminal_services

Good luck...
