Could not Launch the Farm configuration wizard

I have installed  SharePoint foundation 2010  on the  Windows 2008 R2 Server  with  MSSql 2008 R2.  The is not a domain controller and it is workgroup server.

Installation went through without any issues.  Now I am facing problem in Launching Farm configuration wizard.

I am trying to launch the farm configuration wizard in two way

A.

1.  Open internet explorer
2.  Enter the sharepoint server address
3.  Login with user name and password
4.  In share Point central administrator web site,  click on configuration wizard – it returns blank page. 

B.  Start - Programs - SharePoint 2010 Products - SharePoint 2010 Products Configuration Wizard  

        In continue with configuration wizard.   After few steps of default values,  it opens the internet explorer  and ask for the user name and password.   After passing the user and password credentials,

        System gives error  as  permission denied.

I have read lot of solutions for this issue and applied the same.  Most the solutions suggested that the username should have some roles rights in sql and windows etc.  I have given all possible rights to the user and trying to get this launching wizard and there  is no luck.  

I would appreciate if you could help me to sort out this issues.

Thanks & Regards.
