Wsus Error 0x8024400e

Hola a todos:
Tengo un WSUS sp1 sirviendo a casi 70 equipos las actualizaciones, pero
tengo un problema con 7 de ellos:

En la consola de administración aparecen como equipos "Aún sin informar".
Si actualizo desde microsoft no parece que haya ningún problema, pero en
la consola de administración siguen sin cambiar de estado.
Si los fuerzo a actualizar desde el WSUS de la red me dan el error
0x8024400e, no se actualizan y en el windowsupdate.log aperece la
siguiente secuencia:
