Although it doesn't hurt to have an XP CP, I'd try two alternatives first:
1. Boot into Safe Mode, and try the (normally hidden) user "administrator". By default it doesn't have a password, and most people don't add it. If it works, you can change all other passwords as you like.
2. Download a program called ntpasswd from http://pogostick.net/~pnh/ntpasswd/ and reset the password you don't know now.
Both alternatives are free.

Hello, I work at a motel and we have a dell dimension e521 sitting in our lobby. The previous owners of the motel did not leave us with the amin account password so I need to reinstall win xp. I have been searching online for the compatible win xp disk and I think I found it but being a noob that I am, I am not entirely sure. So I ask you guys if this cd will reinstall win xp correctly on dell dimension e521.
Dell dimension version of win--------> win xp pro 2002 sp2 v2096
The new win xp cd that i think would work.-----> Microsoft Windows XP Professional SP3 (Service Pack 3) Pro COA CD Full Version
