Todas esas peticiones vienen de diferentes ips, ademas de la del mismo servidor (el servidor unicamente funciona en intranet, no tiene salida a internet), alguien sabe que tipo de servicio/programa/virus realiza este tipo de peticiones? e estado revisando en don google, y no dice nada al respecto.

Una cosa mas, quizas no sea el lugar correcto para preguntar esta segunda cosa pero mejor lo ago

Tengo esta configuracion en el servidor, y mi sesion me la termina "sin motivo" aparente, el usuario nunca le da en cerrar sesion, esta establecida para que termine a las 12 horas de iniciar sesion, sin embargo me la termina de la nada y en tiempos variados (1 hora, 2 horas, 5 horas, en ocaciones cada 15 o 20 min)


Gracias de antemano por todo
