Login password issue? IIS

Okay, here's the deal... I run IIS 6.0 (Windows Small Business Server 2003)... Gallery 1.x was installed and working beautifully. I installed a new server, copied over all my websites to the new server. Only one website uses Gallery 1.x. Once the transfer was complete, the Gallery didn't work. No duh, forgot to instal PHP, configure IIS and change the paths of the Gallery 1.x files in the code. Once I did this, everything worked fine. I was able to view the previous albums.

Everything's working except the login ID and password. I know for certain I'm typing in the correct ID and password.

I didn't rerun the configurator for Gallery, like I said, everything working fine. I just can't log in. If I just copied over the files, why would the password have changed? Is there a way to reset it?

Thank you
