Windows XP Log on Problems?

I just got through setting up Windows XP Pro w/ SP2-- and I had 2 accounts set up, Administrator, and Guest, when the log on screen appears, it only let's me click Guest, "Administrator" isn't even listed. I put Visual Studio.NET 2003 on here as well and clicked the asp.net and made it administrator as well, could that be my problem, any solutions??? Please help me, I have never had this problem before with XP, please help!

try log in Windows Safe Mode. Then add a new user with Administrator access.

To get into the Windows 2000 / XP Safe mode, as the computer is booting press and hold your "F8 Key" which should bring up the "Windows Advanced Options Menu" as shown below. Use your arrow keys to move to "Safe Mode" and press your Enter key.

from the log on screen hit ctrl-alt-del twice and then you will get a standard log on screen.
what i'd do, is purchase a copy (or even download it, it's FREE) of LINUX OS, and ditch windows and surprisingly you'll never have a problem again....
Either boot up into Safe Mode (before you get to the login screen, it'll tell you that some key like F2 or F8 will give you different login options), or:

When XP boots up and you are at the logon screen, press the CTRL+ALT+DELETE key combination twice during the friendly logon interface to use the conventional Windows 2000 logon interface.

Now, in the Username box, make sure Administrator is showing in there.. If you never set up a password when XP was installed, leave the password area blank and just press enter.. That should get you to the true system admin screen.
u can only log in guess well go to control panel in da start menu and click users account
