Можно попробоваь через net send но это будет сетевая рассылка, а не только терминальным пользователям.

How do I send a message to a Terminal Server client? Terminal Server supports two methods of communicating with a Terminal Server client process. The first is via the GUI: 1. Start the Terminal Services Manager MMC snap-in (Start - Programs - Administrative Tools - Terminal Services Manager) 2. Expand the domain - Server and a list of connected processes will be shown 3. Right click on the process and select 'Send Message' from the context menu Click here to view image 4. You can then enter a title for the message and a message text. Click OK To send from the command line perform use the MSG command, msg <user> [/time:<seconds>] [/w] [/server:<server name>] <message> For example: C:\> msg savillj /w Get off that computer John! The /w switch will force the administrators session to pause until the user has clicked OK to the message.
