I would use the program TweakUI: Found Here: http://tinyurl.com/h8zs
Go ahead and install the program. When finished the program will show up under Start>All Programs>Powertoys for Windows XP>TweakUI
When the program is running you will see a listing on the left side. Logon will be one of them. Click the + next to it. You should now see Autologon, go ahead and click this. A screen on the right should have the option Log on automatically at system startup. Check the box and enter your username in the box. You can also set a password if you want. Click Apply and try a reboot. It should work.
