event viewer - security

[eastside]

I am seeing some "events" occuring on my computer during times when I am not using it (the middle of the night).
I do not understand the Microsoft explanations of the events.
Is this normal to see something like this in the event viewer under the security menu:

type: success audit
category: privilege use
event: 576
user: network service

and this

type: success audit
category: logon/logoff
event: 528
user: network service

Is this spyware or someone logging onto my machine ???
Thanks for any help

Not spyware, they are perfectly normal audit events for the network service user. Many background services run as "network service". This is a built in user/service name.

In affect it is someone logging in/out but only to validate the server user from an audit perspective. If it failed then I would be concerned. You see it some on standalone pc's but it's very common to see that event in the logs of domain controllers.

fwiw
