This article describes how to enable cursor blink when running Web-to-Host sessions on a Windows terminal server.

Problem:

When running W2H (Web-to-Host) sessions on a Windows 2003 terminal server, the display cursor doesn’t blink. Why is this, and how can we make it blink again?

Resolution:

For bandwidth conservation reasons, the cursor blink is disabled by default for applications running on a Windows 2003 terminal server. Perform the following steps to enable cursor blink:


  1. Make a backup copy of the registry.
  2. On the Windows Terminal server open the registry editor, regedit.exe.
  3. Select this registry key: HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Terminal Server
  4. Right-click on the key, and select New | String Value.
  5. Type CursorBlinkEnable for the name, and set the value to “1”.
  6. Close the registry editor.
Future terminal server sessions will now allow the Web-to-Host display cursor to blink.
Note: This registry change will only work on a Windows 2003 terminal server with ServicePack 1 or higher applied. For more information, see the following Microsoft knowledgebase article:  http://support.microsoft.com/kb/873418
