  • Remote Desktop Problem

    Hi All
    I am trying to make a remote desktop session into a SBS 2003 server over a VPN.
    I am able to make a VPN connection into the remote network from a machine in my office and then a remote desktop connection, using the administrator account for the SBS 2003.
    I am able to make a VPN connection into this network from a machine in another office. However, I am unable to make a RDC from this particular machine
    getting the error message 'Client could not connect to the remote computer ........' .
    I am using the same administrator account when attempting the connection but without success.
    I also cannot ping the SBS Server in this instance which I presume I should be able to do.
    The IP I have been assigned in this case lies within the allowed range.
    Any suggestions greatly appreciated since I have spent a lot of time on this already!

    Do you use the same IP range in both offices? Did you tried to change the MTU?

      Thankyou for responding - I am by no means an expert in this area so any help is greatly appreciated.
      If the VPN remote clients are set to obtain an IP in both cases, I would think that they would be assigned an IP in the appropriate range in both cases. (Note that I am connecting to the same network in both cases - but from different locations). Correct me if I am wrong.
      I haven't checked the MTU settings as yet - but will as soon as I am able.

        If you use on you local network 192.168.0.0/24 (for example) and you try to connect to remote LAN that use 192.168.0.0/24 the connection will be drop due routing problem.
        Some firewalls allow you to overcome this issue (Check Point NGX for example) but it not a easy setup routine.

          You are right - the IP range is the same in both cases. Is this a common problem and is the use of a suitable product like NGX the normal solution? We want to enable VPN connections (with Remote Desktop) from a number of remote lans where we have no control over the IP range.

            Hi, you can do this with the fairly inexpensive Sonicwall TZ170 with the Enhanced OS. You can created a 'Hide Net' and so to your remote VPNs your network seems to be on a different range. Bingo!

              Or you can avoid VPN altogether and use <FQDN>/remote and it will allow you to connect to your desktop computer much like pcAnywhere used to. IMHO it's also much safer.
              TIA

                Thanks for the help so far.
                I have tried using <IP>/remote with the admin account and the Remote Web Workplace page opens but when I try to 'Connect to server desktops' (or any other desktop!) I get the following message:
                " The client could not connect to the remote computer. Remote connections might not be enabled or the computer might be too busy..............."

                I was able to connect from the internal network.

                I have spent considerable time on the net looking for a solution - lots of suggestions, none of which solved the problem. I'm looking for a good troubleshooting document but haven't had much luck so any suggestions/guidance appreciated.

                  As stated before if both subnets are the same range you will not be able to successfully connect.
                  TIA
