    Hi,

    1. Is there any way to block RDP connections that I could connect only from a specific computers in windows server 2003, something like on ISA server where I can set from which PC I can remotly connect to the server. I've looked into terminal manager but I couldn't find. I know that I can change the scope in the firewall (btw is it to use with singel IPs or I need to specify whole range from which I can connect) but are there any setting directly on terminal manager?

    2. How to change the port of remote desktop on ISA server?

    Regards
    Sebastian

    You normally, allow only certain Users to access Remote Desktop rather than certain computers.

    RDP uses port 3389. Block this on the clients firewall. Probably a better way but this will do the trick. Jim

    If you want to change the port number that the actual ISA server will listen for remote deskop, then you’ll need edit the following register key

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber

    Double click this and set it to the new port number you want (Port number is in Hexadecimal) d3d = 3389.

    Or if your wanting to connect to Machines behind the firewall you can create a publishing rule to publish certain IP's on a specific port, which will then be routed internally on the default port, i.e publish computer1 for protocol RDP on port 9999, users types ISASERVER:9999 to connect to computer1.
