SYMPTOMS

In a Terminal Services session that connects to a Microsoft Windows Server 2003-based terminal server, you cannot use a keyboard shortcut that uses the ALT GR key to type an extended character.

Extended characters have an ASCII value that is greater than 127. For example, the euro symbol (€) is an extended character. Typically, this problem occurs if you apply Windows keyboard shortcuts to Terminal Services sessions.

2. In the Remote Desktop Connection dialog box, click Options, and then click the Local resources tab.

MORE INFORMATION

When you use a keyboard shortcut that uses the ALT GR key, Windows uses hooks. Hooks modify messages before they are sent to a program window.

When you redirect Windows keyboard shortcuts to a Terminal Services session, the client uses hooks to determine which shortcuts to send to the terminal server and which shortcuts to send to the client computer. Occasionally, some parts of these messages are delayed. Therefore, the extended character that you typed does not appear in the program window.
