You will need to listen on a socket on each client machine.  Then have the server send the client a special message of whatever kind you like, then once the client gets it, trigger:

PostMessage(HWND_BROADCAST, WM_SYSCOMMAND, SC_SCREENSAVE, 0);

To start the local screensaver.

Read at http://www.delphi3000.com/articles/article_3072.asp the 'Shutting down a machine acrosa a network'.
This sample explaine how to send a command over a net.

Replace :

if Incomming = 'S' then // Shutdown Protocol
    ExitWindowsEx( EWX_FORCE or EWX_SHUTDOWN, 0 );

with

if Incomming = 'S' then // ScreenSaver Protocol
    PostMessage(GetDesktopWindow, WM_SYSCOMMAND, SC_SCREENSAVE, 0);




 Or:
SendMessage(handle, wm_syscommand, SC_SCREENSAVE, 0);
