Windows XP Remote Connection from Home to Office

Hi all, I'm looking to give out 500 points if someone will help me out in the next couple of minutes setting up a connection so that I can connect from my home computer to the office using the Remote Connection program that came with Windows XP.  Both machines (at Home and at the Office) are running Windows XP Professional.  In the office I have a Linksys Router.  

Can it be done?

Thanks!

-Dom

You will need to forward port 3389 on your linksys router to the internal machine

on the linksys router set the portforwarding (port 3389)  to the ip address of your office pc
install a dyndns client on your office pc (see dyndns.org)
open the RDC and typ the IPaddress or <registeredname@dyndns.org>

You have tried to connect to the external ip (the one assigned by your isp) from home?
You can not do this from inside the LAN as most linksys routers don't support LAN loopback

yeah I have tried nothing worked.  I'm trying to see what you (stevenlewis) and elconomeno suggested.  I'm looking at the dyndns.org site  Give me a few, if any one of you have either AIM or MSN Messenger and are willing to chat one on one to help me out, i would highly appreciate it.  Also if possible can someone test the connection to see if it works?

Thanks,

stevenlewisCommented:
Dom, according to the MA we must do all the work here (no AIM or messenger)
but to see if the port is open go here
www.grc.com and test your shields (have remote desktop listening)

ok i ran the test and I cant find the open port.  Everything is "Stealth".  I opened port 3398 on the Router and forward it to my IP address.  What else needs to be done?

oh and i dont know if this matters but at the office I do have a new server running Windows 2003 Small Business Server; but I do not want to connect to the server from home, I want to connect to the workstation from home!

Thanks

ok i'm installing it now... I'll let you know what comes up!  Thanks

OK I have installed the file.  Now what should I do?

stevenlewisCommented:
I use dyndns, but only  update it rarely. I run an ftp server for friends and family, but only run it when I know they need to connect (don't leave it running)
I set a static ip for my server (internal ip) and forward the port (same principal as this)
I would offer to test the connection but don't thinki it's a good idea for you to post your external ip address in a public site like this (invites trouble)
0
stevenlewisCommented:
OK, it should update your ip to dyndns
then when you are home use desktop remote to connect to the ip listed at dyndns
example
if your external ip is 267.279.0.255 (I know this is a fake ip)
and your internal ip is 192.168.0.1 then  you would connect to 267.279.0.255 and the router would forward it to 192.168.0.1

OK how do i set the static ip for the server and forward the port?  

If you ok with it, if you can give me your email address i can give you the external ip address to test the connection

Let me know

Thanks

stevenlewisCommented:
Hmm, If I remember linkjsys uses 192.168.1.1 as the default for the router, so you would have to set your pc to
192.168.1.10
mask 255.255.255.0
default gateway
192.168.1.1
dns server should be the dns server assigned by your isp or 192.168.1.1
you can check some of this info by going to a prompt and type
ipconfig /all
check the default gateway and dns servers
or you can post here and I will tell you what to set the ip info to

3389 is enabled both ways and has the ip address of the machine!  

Is that all that has to be done?

How to we update the dyndns so that I can get in with no prob?

stevenlewisCommented:
that is what the client you downloaded from dyndns is supposed to do, but I will have to run it to check

dieseldomAuthor Commented:

i have set it up but i want to try it , can u help me out?

stevenlewisCommented:
I really don't want to give it out here (holy spam batman)
use grc to test the port

rshooper76Commented:
If you are still having problems with this let me know an I will try to help you out.  Basically you will need to be able to see the computer you are connecting to ont he network, either througha  public IP address or though port forwading.  Also you will need to Enable Remote Logons on this machine.  I am not sure if the XP Firewall will block this, mine is turned off by default.

ok i have no clue what else has to be done.  so far I haven't gotten no where!!!

stevenlewisCommented:
But you can't test this from inside the LAN, you have to try it from outside (like at home)
0
dieseldomAuthor Commented:
I'm not testing it from inside the LAN.....I have a separete office on the third floor with a standalone machine and its own high speed internet connection.  The dyndns process is probably not working.
0
stevenlewisCommented:
OK, hmm then you can scan the ports of the router that the other machine is connected to?
try this port scanner
http://www.bluebitter.de/download/BluesPortScan.zip
scan the dyndns ip
0
stevenlewisCommented:
BTW, you did the dyndns update from the other machine (the one conencted to the router)?
0
dieseldomAuthor Commented:
ok am i supposed to install that program from dyndns on the machine that i'm using to connect to the office?  
0
stevenlewisCommented:
No, on the "host machine" the one that will be listening (assume it;s the one in the office you want to conect to)
0
dieseldomAuthor Commented:
yeah i did that.  the program is installed and its updated cuz i logged on to the dyndns.org site to check and everything is right
0
stevenlewisCommented:
OK, get the port scanner I posted, and from the machine upstairs (outside the LAN) scan port 3389 and see if it is open (make sure remote desktop is listening on the machine that you are trying to connect to)
0
dieseldomAuthor Commented:
ok what ip address do i put in the field in the port scanner?
0
stevenlewisCommented:
the one listed at dyndns
0
dieseldomAuthor Commented:
ok hold on
0
stevenlewisCommented:
also do not update the dyndns entry from the machine upstairs, if yoou do it will give it that ip address and not the one for the LAN router
