how do i change the pass word without actually being the admistrator nor knowing the password

In short, you can't - And with good reason. For more information on possible legitimate ways of changing or recovering your password, here's the Microsoft Knowledgebase Article on it:

How to log on to Windows XP if you forget your password or if your password expires

To log on to XP, you need a valid User Account - That means a username and password. There are other means of recovering passwords, though I won't discuss them any further here for obvious reasons.

Ask your administrator is my only advice. If it were easy to do this, then there would be no point in accounts and an administrator
