Configuring the Terminal Services Client (Windows Embedded CE 6.0)

  • 项目

1/5/2010

The Windows Embedded CE Terminal Services Client (CETSC) is configured by the Terminal Server Client registry key, HKEY_LOCAL_MACHINE\Software\Microsoft\Terminal Server Client. This registry key is defined in rdp.reg at %_WINCEROOT%\PUBLIC\RDP\OAK\FILES.

For more information about CETSC, see Windows Embedded CE Terminal Services Client (CETSC).

CETSC Configuration

The following table shows the named values that are used to configure CETSC on a Windows Embedded CE powered thin client.

Value Description

CEConfig

This value indicates whether CETSC runs in the Windows Thin Client Shell.

The following list shows the available settings:

  • "WBT" indicates that CETSC is running in a Windows Thin Client Shell. This is when SYSGEN_WBTSHELL = 1.
  • "Maxall" indicates that CETSC is not running the Windows Thin Client Shell. This is used in all other OS designs.

The default setting is "WBT".

The following list shows the behavior when WBT is set:

  • File change notifications through protected server library (PSL) calls are disabled.
  • The Windows Thin Client Shell does not display the CETSC UI.
  • Keyboard hooks are disabled for the Windows Thin Client Shell.
  • Additional registry migration occurs for Windows thin client OS designs because the connections are started through registry settings and not through .rdp files.

The following list describes issues that a Windows thin client might encounter if this value is set to "Maxall":

  • The Filesys.exe may crash when file storage redirection is enabled and the clipboard tries to copy a file.
  • The CETSC UI appears in the Windows thin client when the dialog box for enabling file storage redirection is canceled.
  • Keyboard shortcut messages might be sent to remote sessions.

BitmapPersistCacheLocation

This value indicates the location of the bitmap cache.

The default value is \Temp.

DisableFileAccess

This value indicates whether the user has access to the local file system.

A value of 1 indicates that access to the local file system is disabled and the Save As and Open buttons are not available in the UI. A value of zero (0) indicates that the user has access to the local file system.

The default value is 1.

FullScreenAlways

This value indicates whether full-screen mode is enabled.

The default value for a thin client is 1. You should not change this value.

When this value is 1, windowed mode is disabled and the session is always run in full-screen mode.

The following registry key example shows the registry settings in rdp.reg that associate .rdp files by using CETSC.

[HKEY_CLASSES_ROOT\.rdp]
    @="rdpfile"
[HKEY_CLASSES_ROOT\rdpfile]
    @=LOC_RDPCONNECTION
[HKEY_CLASSES_ROOT\rdpfile\DefaultIcon]
    @="\\Windows\\cetsc.exe,-101"
[HKEY_CLASSES_ROOT\rdpfile\Shell\Open\Command]
    @="\\Windows\\cetsc.exe %1"

For more information, see RDP Registry Settings.

CETSC User Preferences

When a thin client includes the Windows Thin Client Shell and is deployed and run, user preferences are stored in the HKey_Current_User\Software\Microsoft\Terminal Server Client\Default registry key.

Note

This information is comparable to what is included in the .rdp file when a shell other than the Windows Thin Client Shell is used.

The following table shows the named values in this registry key.

  2. In Files of type, select All Files.

  3. Navigate to the %_WINCEROOT%\PUBLIC\RDP\OAK\FILES folder.

  4. Select rdp.reg and click Open.

  5. In the rdp.reg, type directly in the file to add the named values in the HKEY_LOCAL_MACHINE\Software\Microsoft\Terminal Server Client registry key or in the HKey_Current_User\Software\Microsoft\Terminal Server Client\Default registry key.

  6. On the File menu, select Save rdp.reg.

Note

During the build process, makeimg.exe processes all .reg files in the build directories to create a single file, Reginit.ini. Reginit.ini forms the basis for the system registry.
