Hola grupo,

Tengo un servidor Win 2000 server y lo que quiero es que de 13:00 a
15:00 se bloquee automaticamente, es decir, apretar CRTL + ALT + Supr y
luego bloquear equipo (ALT + O).
He probado con sendkeys "^(%{DEL})",true ; sendkeys "(^%{DEL})",true;
sendkeys "^(%)({DEL})",true y nada de nada.

¿Alguna sugerencia?, aunque no sea por código, si es por tareas

programadas

de windows o otros medios es lo mismo.

Desde ya, gracias.

Dani

Copia este código, saludos.

Solo tienes que llamar a los procedimientos ShutDownNT, RebootNT o LogOffNT,
en tu caso el LogOffNT.

Eso cierra los programas y vueve a pedir el usuario. En XP si que
funciona, por lo que he leido por ahí, creo que tambien funcionará en 9X.
