Passwords
Passwords are a common means of controlling access to your computer and various secure web sites. You need to make your password as difficult to guess as possible since once someone guesses your password (or obtains it via a brute force attack) they have complete access as if they were you. A good password is at least eight characters long and contains both upper and lower case letters and numbers. The password should not contain dates or any word that can be found in a dictionary.
Windows NT/2000/XP/2003 has much better security than Windows 95/98/SE/ME because you can force people to logon and you can restrict access to data on the computer to only that which belongs to the user who is logged on.
You should rename the Administrator login to something else so that both the logon id and password need to be guessed, not just the password. Never log on with an administrator account for everyday use.
You should disable Guest access.
