XP Password Lock-out

I exceeded the number of allowed Password violations on my XP Professional desktop and have locked out my ID for 42 days. I am running Fat 32 and do not have any personal settings that I am concerned about losing. I do not have a separate administrator sign-on established. I also did not create a password diskette. How can I either reestablish my acount that is locked out or establish a new account. As an aside, I have the entire harddrive established as a share on my home network, so I can write to the hard drive, if that is of any benefit.

Thanks in advance
