SYMPTOMS

On some keyboards, you must press the ALT key that is on the right side of your keyboard to generate many extended characters such as the at sign (@) or the backslash (\). For example, when you use a German keyboard, press and hold the ALT key that is on the right side of your keyboard and then press the Q key to type an at sign.

When you use an MS-DOS-based program in a Terminal Services session, any key that uses the ALT key that is on the right side of your keyboard as a qualifier does not generate any characters. However, when you use the same MS-DOS-based program locally, the program works.

CAUSE

When you work locally, the ALT key that is on the right side of your keyboard sends as a single keystroke from the ALT key that is on the right side of your keyboard to the program. When you run the same program in a Terminal Services session, the ALT key that is on the right side of your keyboard is translated into the CTRL+ALT key combination.

This key combination is not handled correctly by the Windows NT Virtual DOS Machine (NTVDM), which provides keyboard input to MS-DOS-based programs.
