Dear Managers :

Please can help me ?

Last day, my server with Digital Unix 4.0F is halting without
explication, this occurs each 20 minutes aprox. I would want to know if
exists some record about events such as halt or reboot commands, because
the posibility for a intruder access exists.

Thank you for your reply.

Best Regards.

Att.
