Dell Wyse ThinOS Version 8.5 Hotfix Administrator’s Guide

Configuring RDP connections

1. From the desktop menu, click System Setup, and then click Remote Connections.
   The Remote Connections dialog box is displayed.
2. In the Broker Setup tab, from the drop-down list, select the Broker type as None.
3. Click RDP connection protocol, and click Configure.
   The Default RDP dialog box is displayed.
4. Click the Connection tab, and use the following guidelines:
   
   1. Connection Description—Enter the descriptive name that is to appear in the connection list (38 characters maximum).
   2. Host Names—Use the list to select the valid DNS server name or the IP address of the server to which the thin client connection is to be made you can also use Browse next to the box to make the selection you want. For example, a list of WTS servers on the local network from which you can select.
      NOTE:The server name may be resolved using one of two mechanisms: DNS, and WINS. DNS uses the default domain name in the network control panel to attempt to construct an FQDN but will also try to resolve the name without using the default.
   3. Console mode— Select to set the RDP connection with Windows Console mode.
   4. Display Resolution— Select the display resolution for this connection.
      Colors—Select the color depth of the RDP session. If High Colors (16-bits) or True Colors (32-bits) is selected and the RDP server does not support this color depth, the thin client renegotiates the color depth to the lower value for example, 256 Colors (8-bits). The highest is 32-bits, if the hardware supports this color depth.
   5. Window mode on 1 monitor or Full screen span all monitors—Select the initial view of the session in window mode or full screen mode.
   6. Auto-connect on start-up—When selected, automatically connects the session on start-up.
   7. Re-connect after disconnect—When selected, causes the thin client to automatically reconnect to a session after a non-operator-initiated disconnect. If selected, the wait interval is that set in the Delay before re-connecting box (enter the number of seconds 1 to 3600) or the user profile for yes (20 seconds) or seconds. The default is 20 seconds, if there is no INI file description of this connection, or is a Stand-alone user, or is simply omitted.
      You can reset the options in the Connection tab of the Connection Settings (RDP) dialog box. To reset, click the Reset VM command button. This command button is located in the upper-right of the dialog box. It appears only with a VDM broker connection.
5. Click the Logon tab, and use the following guidelines:
   
   1. Logging on area—Enter login username, password, and domain name. If these boxes are not populated, you can enter the information manually in the RDP server login screen when the connection is made. Use the following guidelines:
      • Login Username —Maximum of 31 characters is allowed.
      • Password—Maximum of 19 characters is allowed.
      • Domain Name—Maximum of 31 characters is allowed.
   2. Application (127 characters maximum) and Working Directory (63 characters maximum)—Enter an initialization string and arguments, including an associated working directory, that you want to start automatically on the server when the connection is made.
   3. Use TS Gateway—Enables the use of Terminal Services Gateway (TS Gateway) server when connecting. If required, then enter the IP address or URL of the TS Gateway server in the Server name box. You can also enable Use Same Info (if the server credentials are the same credentials as your Remote Desktop Credentials (Host remote computer credentials) in the Login Username, Password, and Domain name fields) or disable Use Same Info and enter the Server name, User name, Password, and Domain name of the TS Gateway server if required.
      NOTE:A TS Gateway server is a type of gateway that enables authorized users to connect to remote computers on a corporate network from any computer with an Internet connection. A TS Gateway server enables Remote Desktop connections to a corporate network from the Internet without having to set up virtual private network (VPN) connections. Ask your network administrator whether you need to specify a TS Gateway server.

      • User Name—Enter a user name for the connection.
      • Password—Enter the password.
      • Domain—Enter the domain name.

      NOTE:The user name, password, and domain name fields are optional. If you leave any of these fields blank, interactive login is required and users must enter the information at the login time.

   1. Wallpaper—When selected, disables the desktop wallpaper.
   2. Menu / Window animation—When selected, disables the menu or window animation.
   3. Theme—When selected, disables the desktop themes.
   4. Show content when dragging—By default, when you grab a Window by the title bar and move it around, the contents of the window will move with it. Select this to disable this content view so that only the outline of the window moves when dragging it, until you drop the window. This option can be beneficial, as it uses less processing power.
   5. Font smoothing—Converts vector text to bitmap for better display.
   6. Auto-connect to local devices—Select any options (Printers, Serials, USB, Smart Cards, and Disks) to have the thin client automatically connect to the devices.
