I believe you can use "msg <username> <message>" On Windows 7 if you go to a command prompt and type msg, you should get the syntax. Good luck. Firm.

I would usually just use the email feature but when the MSU Mail is down and I need to let people know that and keep them updated I need another way to communicate. Any ideas or suggestions would be appreciated. Server = Windows Server 2008 & Server 2008 R2 Desktop units = Windows 7 Pro No exchange server obviously Thanks
