is ther a limit for remote desktop connetions tunneling over VPN

Discussion in 'Server Networking' started by Jotita SBS 2003 Admin, Apr 30, 2008.

  1. I have Window Server 2003 in main office with 12 Desktops PC with XP Pro.
    Sometimes the people wants to connect outsite the office with the pc at the
    office over the VPN and then remote desktop but I have a problem when there
    are more that 2 or 3 connections concurrents the remote desktop or the VPN
    connections droped.
    The question is how many connections can manage the server for externals
    remote desktop connections over VPN..

    Thanks a lot for help

  3. Thanks for the answer

    I know in Remote Desktop Administration it is max 3 connections, but you
    mean If I have 25 licenses then 25 people can connect to their own Remote
    Desktop over the VPN?

    Jota,

  4. Veering slightly OT....since you're using SBS, why are you using VPN to get
    to RD anyway? You've got Remote Web Workplace.

    You should always post SBS questions in microsoft.public.windows.server.sbs
    even if you choose to *crosspost* elsewhere - SBS does many things its own
    way. I'm setting up my reply to crosspost to that group.

  6. (passes Phil some coffee)

    XP Pro PCs are *one* connection at a time - either remote or local.

    RD to a Windows 2003 server allows *three* concurrent connections (presuming
    one of them is /console)

    W2000 running TS in admin mode allows for *two* remote and one local console
    connection.

  7. Ok here go again… my problem is:

    I have server SBS 2003, and 12 PC with XP PRO.

    Most of the people travel and they want to connect to their PC's in the
    office from wherever they are.

    I setup VPN in each laptop PC from them in order to connect to server and
    then with local IP they connect to their own Desktop PC’s; so I need to know
    if the 3 connections maximum is applicable for this case or if there is a
    limit for this kind of connections, I mean Remote Desktop over VPN.

    I don't know if I don't understand your answer but just to need how many
    connections I can use.

    Thanks

  9. Please read my first reply to your post. You shouldn't be using VPN for this
    at all - you should be using RWW - and you should be posting in
    microsoft.public.windows.server.sbs for the most expert help with this.

    PPTP VPN is something I don't generally use or recommend - and it is not
    needed for Remote Desktop to your workstations on an SBS2003 domain, nor for
    remote Outlook use. It is limited and not very secure. Use Remote Web
    Workplace.

  11. Then that is different.
    They only need the one RDP Connection (per desktop).

    The number of VPN connections is equal to the number or PPTP and L2TP
    "ports" you have available in the RRAS MMC Admin Tool. It can also be
    limited by the number of "free" addresses you have available to give to the
    VPN Hosts. But neither one of these will make an exisitng connection
    "drop",..they will only prevent a new one from occuring.

    There is no "specific" thing as "Remote Desktop over VPN" in the same sense
    that you might say "Netbios over TCP/IP". VPN is *oblivious* to what is
    being done over it,...it does not care squat about what you do over the VPN
    connection once it is "up".

    One thing you might want to try,...create a completely separate shortcut to
    the RDP Client. Modify the Commandline with the /console parameter so it
    looks like this.

    %SystemRoot%\system32\mstsc.exe /console

    Give the shortcut a specific name so the user does not confuse it with the
    original one. Try connecting using it.

  12. Another thing to consider with VPN connection problems....

    If you have a crapply, low quality, Home-User, consumer grade, broadband
    "router" between the Windows [VPN] Server then that may be the problem.

    Posting SBS questions in this group is not the best idea as SBS does so many
    things its own way.

  14. I don't know. SBS lives in its own little world with some things. That is
    way you should listen to Lanwench and ask these questions in a Group
    dedicated to SBS.

    Thank you for the answer

    My finally question will be, is there any relation between the
    licenses numbers in SBS 2003 with the number of remote desktop
    connections??

    Thanks again

  15. I don't know about dropping connections but I would check your router. Many
    cannot support multiple GRE (protocol 47) sessions.
