MessageCenter

This script uses Windows Forms to present a GUI for sending messages to remote computers on a network using msg.exe.  You can send to a single computer, multiple computers entered manually, multiple computers from a text file, or you may scan Active Directory for active computers on the network. You can also run this script to change the registry key value AllowRemoteRPC on local computers you would like to send messages.  In a domain environment, you can run this script from a workstation or server with the GPMC installed and create a Group Policy object to affect this change for you.
