I believe you already need to be the administrator for pwdump to work; however a privelage escalation tool like PipeUpAdmin ( http://www.dogmile.com/files/#PipeUp )might help. I think this was patched with SP2, so if you have an earlier installation than that I think it'll work. It basically adds the current user to the administrators group which will then allow you to make whatever changes you need to make; or at the very least will get pwdump working. Hope this helps.
