    So I am at work here, I don't know what I'm doing wrong, I can't seem to connect to from my work computer to my home computer. I am using XP Pro at work and Windows Vista Business at home. I have followed these steps How to Enable Remote Desktop Connection with Vista | Gil's Method and even unblocked my port 3389 in my wireless router. Does anyone else know what I could be doing wrong? I even added myself to the list of people in the Select Users...

    Do you have any norton (or similar) products running on your home pc?

    Did you also add port 3389 to windows firewall?

    Yes, I checked the box to allow for exceptions for Remote Desktop, do I need to add a port as well?? (even though I did it for the program)

    My coworker has windows xp pro that he is able to remote connection from work, so don't think my work is blocking any ports to do this connection. I am not even able to remote connect from his connection at his house either

    I dont have any norton or anything else running in the background

    If you are using the default remote desktop port then you should be good with how you have it.

    What about my other question?

    The one regarding norton? I dont think so, I did a fresh install a couple days ago and don't have norton or any antivirus type of application running in the background, this is the error message that is popping up:

    "The computer can't connect to the remote computer.
    Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator. "

    And you can connect to your desktop just fine from another computer on your home network?

    The only time I was never able to connect to my computer was when my internet went down, or some crap like norton was on the remote computer, or I had configured my port forwarding wrong on the router.


    How are you connecting anyway? By static IP or by some sort of dynamic dns web address?

    When I used it I would connect by: dynamicdns.com:port#
    or
    staticIP:port#

    You're gonna have to do IP forwarding to your router to point to the Vista computer.

    Every computer under your router is
    192.168.1.10x......
    192.168.1.101
    192.168.1.102
    etc...

    The router is made to block everything so you have to forward any connection from your Internet Address to the right computer on your router.

    Otherwise you can setup a DMZ with your vista machine but then that means your computer is outside the router's firewall and can possibly be hacked.

    So say your Comcast address is 50.183.125.55.

    You would use this address in the remote desktop client. Once you press ok, you will initiate the connection, once it hits your router it will see that you want to connect and it will forward it to the vista machine.

    What kind of router do you have? Like what "thathideousStrength" said, you will have to do port forwarding...

    Sorry to be so blunt here, but did you guy's even read my post? I already did that, my computers internal ip address IS 192.168.1.2 and I forwarded it to 3389 both in the windows firewall (not using the IP just windows settings like the screen shot above and wireless router firewall. I know my External IP address and it hasn't changed since this morning. The router Im using is a lynsys wireless wtr54g

    Thanks, I'll give that a try!

    It turns out that it could not see the port on the outside, i'm going to try and unblock my port on my modem, to see if that will work

    I think my ISP could be blocking my port, cause I tried to add the port in my modem and I still can't connect on the outside, this is the page that I followed to do so:
    Port Forwarding for the Comtrend CT-5071

    If anyone else has any suggestions, please let me know! Thanks!

    If you telnet <your external IP> 3389 (i.e. 1.2.3.4 3389) what happens?

    Also, try using the "allow connections from computers running any version of remote desktop" option in the advanced settings.


    If you can't telnet a firewall/modem problem is the case.

    Vista uses RDP6.0. Make sure you update XP's RDP5.2 to version 6.0.

    Maybe they have their ISP locked down really good...

    Can you try this? Take your computer off the router and straight to the internet modem and see what happens? You'd need to use another computer at someone else's house.

    He wont need another computer, he will just need to go to canyouseeme.org and do another port test.
    If cayouseeme sees it then he should be good to go.

    Not sure if this was covered, but can you even remote desktop when internally on your own network? I will admit, I quickly skimmed the rest of the posts, but I'm pretty sure I didn't see if this test was successful or not.

    When you telnet you'll have to enter the RDP listening port else you'll get your error above (port 23)

    Try:

    telnet 1.2.3.4 3390

    If 3390 is your port still...put a space between your IP and the port number
