Windows XP login password lost

[kylebong 0]

I am using Windows XP Pro, log in to a domain previously.

Recently, the domain down & I've to change my network setting, from log in to domain change to log in to workgroup.

 

So, windows ask my administrator password to log in my computer.

I found that I've lost my password, & username as well.

 

What should I do?

Please advice
