Hi there,
I am a network administrator in a school, recently we have problem with our network, the files of students keep being deleted, one day a teacher saw a message “Hello” came up on the screen and after that the files are deleted automatically in front of her eyes. We are using Windows Server 2003 and Windows Xp SP 2 for the client, I found that I have not updated windows for both server and client for a while, I am doing the updating on the system. How can people get into the system from outside? And the problem is can they see what I send over the network, for example this message?
Thank you
