Quickie: Service Accounts description

January 14th, 2013 No comments

More often I see people (IT admins) not understand differences between Local Service Accounts so I decided to write more about it:

SYSTEM

This account has full access to local computer. It can access network resources with rights (account) of the computer. This account has full access to domain it self when used on Domain Controller.

LOCAL SERVICE

This account has same right as local Users group. It goes to network as annonymous user (null session).

NETWORK SERVICE

It’s almost same as LOCAL SERVICE. Only difference is that it uses computer account to access network resources.

Quickie: Exchange Empty Submission queue

Today I was solving problem with open relay Exchange server. I came to server and it was full of SPAM e-mail messages. I needed to clean all this mess from Submission queue. I used following command:

Get-Message -Filter {FromAddress -eq “<>”} -Server MAILSERVER | Remove-Message

That’s all folks 🙂
