Remote Desktop Connection using Port Forwarding issue. RRS feed

  • Question

  • We're using a static IP at work configured on our router, it handles the DHCP as well.  We have 4 client workstations that have their own preferred IP address.  I've had remote desktop setup for a few years now on only one workstation, and it still works fine.  All workstations are windows 7 SP1 pro 64 bit.  Our server is 2k3.  On the router I've configured port forwarding for each individual workstation.  Also I've gone into the registry editor on each workstation and changed their listening port to correspond with the port I've designated on the router.  We have no firewall enabled across the whole network, only virus protection is McAfee SaaS.  Again with no firewall.  Remote Desktop settings are all checked to allow connections.  Even went into each workstation's services and made sure that the required remote desktop services were started.  Like I said, one workstation works great, I can also get into the server, it's the other workstations that won't work.  When I try to remote in with RDC it says it cannot connect.

    It's got to be something on the workstations end that is blocking the connection I would think.  Every user has the same group policies in the domain as well.

  • 1. Can rou rdp to the workstations from within your LAN?

    2. You run unencrypted rdp on a fixed IP exposed to the internet? That is a MAJOR security risk (even if nothing has happened for years).

  • So, if you have several workstations you are trying to connect to via one public IP address, it seems that you are aware that you cannot do this on the same port.  Rather than changing each workstation to listen on a different port, you need to do this at the router.  Then when you launch the remote desktop client, you have to specify the port number.

    On the router, you would have this config as an example...

    public IP/3389 --> computer1/3389
    public IP/3390 --> computer2/3389
    public IP/3391 --> computer3/3389

  • The user account that you are using to remote into workstation needs to be

    1 - Member of local computer group "Remote Desktop Users" or

    2 - Member of Local computer group "Administrators"

    Check the DNS and make sure that you have correct "A" record for the each computer in question. (no duplicates, one computer with 2 different IPs, etc..)

    What kind of error message do you get if any?
