MS CRM 2011 Install Failure "Action Microsoft.Crm.Setup.Server.InstallConfigDatabaseAction failed."

I'm trying to install MS CRM 2011, and I continually get the

"Action Microsoft.Crm.Setup.Server.InstallConfigDatabaseAction failed.--->System.Security.Authentication.AuthenticationException: Logon failure: unknown user name or bad password.---> System.DirectoryServices.DirectoryServicesCOMException: Logon failure: unknown user name or bad password."

Error. I've tried to uninstall and Reinstall SQL 2008. I have to apply the SP1 patch to it everytime I create an instance - which goes through ok. I don't get any errors in the wizard until it actually starts the installation process. Afterward I continually get this error. Here is a copy of the log:

Thanks, any and all help is much appreciated!

edit CRM 4.0 Was installed and working perfectly fine. I tried fresh install and upgrade of 2011 edition and im having these problems

Are you an administrator on your domain? The CRM setup process adds some groups to AD, so you'll need access on the domain to create those groups if you are the one running the setup process.

Figured out the problem. I had to reassign the Webserver and application roles on the server, then reinstall sql server. That fixed the issue. For some reason the sql server thought the name had changed or something - despite numerous reinstallations. Not sure why or how - but that fixed it
