Past few days I had been trying to fix a problem with Google Apps. While trying to register a new domain with Google Apps we continuously got an error message saying

This domain has already been registered with Google Apps. Please contact your domain administrator for instructions on using Google Apps with this domain.

Surprisingly we never connected both of them before.  This page points to lot of alternatives to find solution and this page specifically had the solution where you can reset your domain admin password via file upload or cname change.

Though this page says to go to control panel login page ( by directly typing in the browser address bar ) and ask for reset password but it never worked for admin password reset. There was nothing that can actually do that.

However when you enter the domain name in the text box provided in the page, I did get an option to reset the admin password via file upload or CNAME changes.

As per the message which I received at the end, Google team will get in touch with me again for fixing it.

So if you are having the same strange problem use this page and use the text box inside it to make it work the right way.

Update : Though nobody contacted us from Google Apps team but next day when i tried following the same step I did get an option to send a reset link to any of my email account instead of saying that somebody from google apps team will get in touch with me. It worked finally.
