HOW DO I... REMOVE OLD NETWORK SETTINGS

Hello,
I have a dell optiplex GX520. I purchased it from a second hand store who told me that they purchased alot of comps from a surplus who in turn purchased them from a school district.

Anyway, my problem is that I now have the computer and I am trying to use it and it seems to have a username and password on it trying to detect and connect me to the network settings.

So my questions are:

1. how to I bypass that user name and password log in screen?

2. how do I delete the network settings on this computer.

3, if I do not know or if the computer has an administrator name and password, how do I bypass that?

4. how can I reset the computer and install windows XP professional if I do not have a start up disk, as I purchased this computer used.

HELP!!!!

    2. how do I delete the network settings on this computer.

    Control Panel \ System \ Computer Name \ Change \ see if the computer is set as member of a Domain or Workgroup.. It will probably be a Domain... and you can only remove a computer from a Domain when it is connected to it...

    You cannot log on after you remove the computer from the domain

    If you change the computer from Domain to Workgroup, you will not be able to logon... you will only be able to if you provide a user name and password that exists in the local computer's database. So, probably the best way to insure you can logon after changing Domain to Workgroup is creating a new user account with administrative rights before restarting the computer.
