Locked out, please help ASAP

Please HELP ASAP! I installed WP, logged in, set up the whole blog, although forgot to change the password. So once the cookies expired or in between me setting up my new domain name, I got locked out. Before I finished transfering my Domain name I set up my blog, finished customizign my theme all that, ALOT OF WORK, all through lan. I know my username ‘admin’ – duh! although I cannot get my password, I have access to every aspect off my server, through lan too! PS: Xampp install is having some issues with the mail function in PHP, I have arranged for sorting that out next week, so I cannot e-mail myself the password. Please help!!!
